Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40770, here are decompositions:

  • 7 + 40763 = 40770
  • 11 + 40759 = 40770
  • 19 + 40751 = 40770
  • 31 + 40739 = 40770
  • 61 + 40709 = 40770
  • 71 + 40699 = 40770
  • 73 + 40697 = 40770
  • 131 + 40639 = 40770

Showing the first eight; more decompositions exist.
