Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526158, here are decompositions:

  • 17 + 31526141 = 31526158
  • 71 + 31526087 = 31526158
  • 89 + 31526069 = 31526158
  • 101 + 31526057 = 31526158
  • 107 + 31526051 = 31526158
  • 137 + 31526021 = 31526158
  • 239 + 31525919 = 31526158
  • 269 + 31525889 = 31526158

Showing the first eight; more decompositions exist.
