Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87992, here are decompositions:

  • 19 + 87973 = 87992
  • 31 + 87961 = 87992
  • 61 + 87931 = 87992
  • 139 + 87853 = 87992
  • 181 + 87811 = 87992
  • 199 + 87793 = 87992
  • 241 + 87751 = 87992
  • 271 + 87721 = 87992

Showing the first eight; more decompositions exist.
