Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545654, here are decompositions:

  • 13 + 31545641 = 31545654
  • 31 + 31545623 = 31545654
  • 43 + 31545611 = 31545654
  • 47 + 31545607 = 31545654
  • 167 + 31545487 = 31545654
  • 263 + 31545391 = 31545654
  • 281 + 31545373 = 31545654
  • 311 + 31545343 = 31545654

Showing the first eight; more decompositions exist.
