Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 958440, here are decompositions:
- 17 + 958423 = 958440
- 47 + 958393 = 958440
- 59 + 958381 = 958440
- 71 + 958369 = 958440
- 73 + 958367 = 958440
- 79 + 958361 = 958440
- 83 + 958357 = 958440
- 89 + 958351 = 958440
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 958,440 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 958440 first appears in π at position 102,328 of the decimal expansion (the 102,328ordinal-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.
