Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87968, here are decompositions:

  • 7 + 87961 = 87968
  • 37 + 87931 = 87968
  • 157 + 87811 = 87968
  • 229 + 87739 = 87968
  • 271 + 87697 = 87968
  • 277 + 87691 = 87968
  • 337 + 87631 = 87968
  • 379 + 87589 = 87968

Showing the first eight; more decompositions exist.
