Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490714, here are decompositions:

  • 7 + 31490707 = 31490714
  • 37 + 31490677 = 31490714
  • 127 + 31490587 = 31490714
  • 331 + 31490383 = 31490714
  • 337 + 31490377 = 31490714
  • 433 + 31490281 = 31490714
  • 457 + 31490257 = 31490714
  • 487 + 31490227 = 31490714

Showing the first eight; more decompositions exist.
