Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470854, here are decompositions:

  • 7 + 31470847 = 31470854
  • 31 + 31470823 = 31470854
  • 61 + 31470793 = 31470854
  • 67 + 31470787 = 31470854
  • 73 + 31470781 = 31470854
  • 193 + 31470661 = 31470854
  • 307 + 31470547 = 31470854
  • 631 + 31470223 = 31470854

Showing the first eight; more decompositions exist.
