Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468118, here are decompositions:

  • 151 + 31467967 = 31468118
  • 181 + 31467937 = 31468118
  • 271 + 31467847 = 31468118
  • 307 + 31467811 = 31468118
  • 397 + 31467721 = 31468118
  • 547 + 31467571 = 31468118
  • 751 + 31467367 = 31468118
  • 859 + 31467259 = 31468118

Showing the first eight; more decompositions exist.
