Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945408, here are decompositions:
- 11 + 945397 = 945408
- 17 + 945391 = 945408
- 19 + 945389 = 945408
- 31 + 945377 = 945408
- 41 + 945367 = 945408
- 59 + 945349 = 945408
- 67 + 945341 = 945408
- 181 + 945227 = 945408
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 945,408 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 945408 first appears in π at position 440,123 of the decimal expansion (the 440,123ordinal-suffix:rd 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.
