Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465244, here are decompositions:

  • 61 + 31465183 = 31465244
  • 67 + 31465177 = 31465244
  • 211 + 31465033 = 31465244
  • 241 + 31465003 = 31465244
  • 271 + 31464973 = 31465244
  • 277 + 31464967 = 31465244
  • 457 + 31464787 = 31465244
  • 463 + 31464781 = 31465244

Showing the first eight; more decompositions exist.
