Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87502, here are decompositions:

  • 11 + 87491 = 87502
  • 29 + 87473 = 87502
  • 59 + 87443 = 87502
  • 179 + 87323 = 87502
  • 251 + 87251 = 87502
  • 281 + 87221 = 87502
  • 353 + 87149 = 87502
  • 383 + 87119 = 87502

Showing the first eight; more decompositions exist.
