Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526974, here are decompositions:

  • 47 + 31526927 = 31526974
  • 53 + 31526921 = 31526974
  • 71 + 31526903 = 31526974
  • 197 + 31526777 = 31526974
  • 251 + 31526723 = 31526974
  • 587 + 31526387 = 31526974
  • 701 + 31526273 = 31526974
  • 761 + 31526213 = 31526974

Showing the first eight; more decompositions exist.
