Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450200, here are decompositions:

  • 37 + 31450163 = 31450200
  • 59 + 31450141 = 31450200
  • 83 + 31450117 = 31450200
  • 97 + 31450103 = 31450200
  • 101 + 31450099 = 31450200
  • 107 + 31450093 = 31450200
  • 139 + 31450061 = 31450200
  • 157 + 31450043 = 31450200

Showing the first eight; more decompositions exist.
