Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002988, here are decompositions:

  • 59 + 1002929 = 1002988
  • 71 + 1002917 = 1002988
  • 89 + 1002899 = 1002988
  • 101 + 1002887 = 1002988
  • 131 + 1002857 = 1002988
  • 137 + 1002851 = 1002988
  • 167 + 1002821 = 1002988
  • 179 + 1002809 = 1002988

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 1,002,988 and was likely granted around 1911.

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