Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 941640, here are decompositions:
- 23 + 941617 = 941640
- 31 + 941609 = 941640
- 41 + 941599 = 941640
- 47 + 941593 = 941640
- 67 + 941573 = 941640
- 79 + 941561 = 941640
- 83 + 941557 = 941640
- 103 + 941537 = 941640
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 941,640 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 941640 first appears in π at position 709,116 of the decimal expansion (the 709,116ordinal-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.
