Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541742, here are decompositions:

  • 5 + 31541737 = 31541742
  • 83 + 31541659 = 31541742
  • 109 + 31541633 = 31541742
  • 131 + 31541611 = 31541742
  • 151 + 31541591 = 31541742
  • 173 + 31541569 = 31541742
  • 179 + 31541563 = 31541742
  • 233 + 31541509 = 31541742

Showing the first eight; more decompositions exist.
