Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 948640, here are decompositions:
- 47 + 948593 = 948640
- 59 + 948581 = 948640
- 83 + 948557 = 948640
- 89 + 948551 = 948640
- 107 + 948533 = 948640
- 191 + 948449 = 948640
- 197 + 948443 = 948640
- 233 + 948407 = 948640
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 948,640 and was likely granted around 1909.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 948640 first appears in π at position 673,369 of the decimal expansion (the 673,369ordinal-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.
