Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564292, here are decompositions:

  • 31 + 31564261 = 31564292
  • 43 + 31564249 = 31564292
  • 163 + 31564129 = 31564292
  • 241 + 31564051 = 31564292
  • 283 + 31564009 = 31564292
  • 313 + 31563979 = 31564292
  • 349 + 31563943 = 31564292
  • 421 + 31563871 = 31564292

Showing the first eight; more decompositions exist.
