Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625544, here are decompositions:

  • 7 + 31625537 = 31625544
  • 37 + 31625507 = 31625544
  • 113 + 31625431 = 31625544
  • 151 + 31625393 = 31625544
  • 163 + 31625381 = 31625544
  • 193 + 31625351 = 31625544
  • 241 + 31625303 = 31625544
  • 263 + 31625281 = 31625544

Showing the first eight; more decompositions exist.
