Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523742, here are decompositions:
- 13 + 523729 = 523742
- 61 + 523681 = 523742
- 73 + 523669 = 523742
- 103 + 523639 = 523742
- 139 + 523603 = 523742
- 199 + 523543 = 523742
- 223 + 523519 = 523742
- 283 + 523459 = 523742
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 523,742 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
