Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495360, here are decompositions:

  • 3 + 31495357 = 31495360
  • 173 + 31495187 = 31495360
  • 251 + 31495109 = 31495360
  • 317 + 31495043 = 31495360
  • 593 + 31494767 = 31495360
  • 647 + 31494713 = 31495360
  • 653 + 31494707 = 31495360
  • 857 + 31494503 = 31495360

Showing the first eight; more decompositions exist.
