Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470136, here are decompositions:

  • 149 + 31469987 = 31470136
  • 233 + 31469903 = 31470136
  • 353 + 31469783 = 31470136
  • 557 + 31469579 = 31470136
  • 617 + 31469519 = 31470136
  • 809 + 31469327 = 31470136
  • 857 + 31469279 = 31470136
  • 1103 + 31469033 = 31470136

Showing the first eight; more decompositions exist.
