Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465136, here are decompositions:

  • 7 + 31465129 = 31465136
  • 13 + 31465123 = 31465136
  • 37 + 31465099 = 31465136
  • 67 + 31465069 = 31465136
  • 97 + 31465039 = 31465136
  • 103 + 31465033 = 31465136
  • 163 + 31464973 = 31465136
  • 349 + 31464787 = 31465136

Showing the first eight; more decompositions exist.
