Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143572, here are decompositions:
- 3 + 143569 = 143572
- 5 + 143567 = 143572
- 53 + 143519 = 143572
- 59 + 143513 = 143572
- 71 + 143501 = 143572
- 83 + 143489 = 143572
- 89 + 143483 = 143572
- 239 + 143333 = 143572
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 143,572 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 143572 first appears in π at position 487,004 of the decimal expansion (the 487,004ordinal-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.
