Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001542, here are decompositions:

  • 11 + 1001531 = 1001542
  • 41 + 1001501 = 1001542
  • 83 + 1001459 = 1001542
  • 131 + 1001411 = 1001542
  • 173 + 1001369 = 1001542
  • 239 + 1001303 = 1001542
  • 251 + 1001291 = 1001542
  • 263 + 1001279 = 1001542

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,001,542 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
