Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507534, here are decompositions:

  • 11 + 31507523 = 31507534
  • 131 + 31507403 = 31507534
  • 167 + 31507367 = 31507534
  • 173 + 31507361 = 31507534
  • 251 + 31507283 = 31507534
  • 263 + 31507271 = 31507534
  • 353 + 31507181 = 31507534
  • 557 + 31506977 = 31507534

Showing the first eight; more decompositions exist.
