Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86788, here are decompositions:

  • 5 + 86783 = 86788
  • 17 + 86771 = 86788
  • 59 + 86729 = 86788
  • 227 + 86561 = 86788
  • 257 + 86531 = 86788
  • 311 + 86477 = 86788
  • 347 + 86441 = 86788
  • 389 + 86399 = 86788

Showing the first eight; more decompositions exist.
