Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1037640, here are decompositions:
- 13 + 1037627 = 1037640
- 29 + 1037611 = 1037640
- 47 + 1037593 = 1037640
- 73 + 1037567 = 1037640
- 83 + 1037557 = 1037640
- 103 + 1037537 = 1037640
- 137 + 1037503 = 1037640
- 151 + 1037489 = 1037640
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 1,037,640 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 1037640 first appears in π at position 672,698 of the decimal expansion (the 672,698ordinal-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.
