Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145964, here are decompositions:
- 31 + 145933 = 145964
- 61 + 145903 = 145964
- 67 + 145897 = 145964
- 103 + 145861 = 145964
- 157 + 145807 = 145964
- 193 + 145771 = 145964
- 211 + 145753 = 145964
- 241 + 145723 = 145964
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 145,964 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 145964 first appears in π at position 122,559 of the decimal expansion (the 122,559ordinal-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.
