Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545062, here are decompositions:

  • 13 + 31545049 = 31545062
  • 61 + 31545001 = 31545062
  • 139 + 31544923 = 31545062
  • 163 + 31544899 = 31545062
  • 313 + 31544749 = 31545062
  • 349 + 31544713 = 31545062
  • 691 + 31544371 = 31545062
  • 739 + 31544323 = 31545062

Showing the first eight; more decompositions exist.
