Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465226, here are decompositions:

  • 3 + 31465223 = 31465226
  • 43 + 31465183 = 31465226
  • 73 + 31465153 = 31465226
  • 97 + 31465129 = 31465226
  • 103 + 31465123 = 31465226
  • 127 + 31465099 = 31465226
  • 157 + 31465069 = 31465226
  • 193 + 31465033 = 31465226

Showing the first eight; more decompositions exist.
