Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88440, here are decompositions:

  • 13 + 88427 = 88440
  • 17 + 88423 = 88440
  • 29 + 88411 = 88440
  • 43 + 88397 = 88440
  • 61 + 88379 = 88440
  • 101 + 88339 = 88440
  • 103 + 88337 = 88440
  • 113 + 88327 = 88440

Showing the first eight; more decompositions exist.
