Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526266, here are decompositions:

  • 53 + 31526213 = 31526266
  • 59 + 31526207 = 31526266
  • 179 + 31526087 = 31526266
  • 197 + 31526069 = 31526266
  • 347 + 31525919 = 31526266
  • 353 + 31525913 = 31526266
  • 449 + 31525817 = 31526266
  • 467 + 31525799 = 31526266

Showing the first eight; more decompositions exist.
