Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546256, here are decompositions:

  • 97 + 31546159 = 31546256
  • 103 + 31546153 = 31546256
  • 127 + 31546129 = 31546256
  • 193 + 31546063 = 31546256
  • 337 + 31545919 = 31546256
  • 397 + 31545859 = 31546256
  • 757 + 31545499 = 31546256
  • 769 + 31545487 = 31546256

Showing the first eight; more decompositions exist.
