Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87764, here are decompositions:

  • 13 + 87751 = 87764
  • 43 + 87721 = 87764
  • 67 + 87697 = 87764
  • 73 + 87691 = 87764
  • 151 + 87613 = 87764
  • 181 + 87583 = 87764
  • 211 + 87553 = 87764
  • 223 + 87541 = 87764

Showing the first eight; more decompositions exist.
