Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471418, here are decompositions:

  • 7 + 31471411 = 31471418
  • 31 + 31471387 = 31471418
  • 61 + 31471357 = 31471418
  • 211 + 31471207 = 31471418
  • 271 + 31471147 = 31471418
  • 367 + 31471051 = 31471418
  • 421 + 31470997 = 31471418
  • 571 + 31470847 = 31471418

Showing the first eight; more decompositions exist.
