Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497222, here are decompositions:

  • 83 + 31497139 = 31497222
  • 89 + 31497133 = 31497222
  • 139 + 31497083 = 31497222
  • 151 + 31497071 = 31497222
  • 233 + 31496989 = 31497222
  • 349 + 31496873 = 31497222
  • 359 + 31496863 = 31497222
  • 431 + 31496791 = 31497222

Showing the first eight; more decompositions exist.
