Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143072, here are decompositions:
- 19 + 143053 = 143072
- 79 + 142993 = 143072
- 103 + 142969 = 143072
- 109 + 142963 = 143072
- 199 + 142873 = 143072
- 283 + 142789 = 143072
- 313 + 142759 = 143072
- 373 + 142699 = 143072
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 143,072 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 143072 first appears in π at position 628,057 of the decimal expansion (the 628,057ordinal-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.
