Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143664, here are decompositions:
- 11 + 143653 = 143664
- 13 + 143651 = 143664
- 47 + 143617 = 143664
- 71 + 143593 = 143664
- 97 + 143567 = 143664
- 113 + 143551 = 143664
- 127 + 143537 = 143664
- 137 + 143527 = 143664
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 143,664 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 143664 first appears in π at position 932,124 of the decimal expansion (the 932,124ordinal-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.
