Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470274, here are decompositions:

  • 53 + 31470221 = 31470274
  • 107 + 31470167 = 31470274
  • 131 + 31470143 = 31470274
  • 461 + 31469813 = 31470274
  • 491 + 31469783 = 31470274
  • 653 + 31469621 = 31470274
  • 743 + 31469531 = 31470274
  • 761 + 31469513 = 31470274

Showing the first eight; more decompositions exist.
