Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143672, here are decompositions:
- 3 + 143669 = 143672
- 19 + 143653 = 143672
- 43 + 143629 = 143672
- 79 + 143593 = 143672
- 103 + 143569 = 143672
- 163 + 143509 = 143672
- 211 + 143461 = 143672
- 229 + 143443 = 143672
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 143,672 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 143672 first appears in π at position 847,336 of the decimal expansion (the 847,336ordinal-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.
