Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029640, here are decompositions:
- 23 + 1029617 = 1029640
- 47 + 1029593 = 1029640
- 71 + 1029569 = 1029640
- 107 + 1029533 = 1029640
- 113 + 1029527 = 1029640
- 167 + 1029473 = 1029640
- 173 + 1029467 = 1029640
- 233 + 1029407 = 1029640
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,029,640 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 1029640 first appears in π at position 340,710 of the decimal expansion (the 340,710ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
