Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507276, here are decompositions:

  • 5 + 31507271 = 31507276
  • 137 + 31507139 = 31507276
  • 167 + 31507109 = 31507276
  • 239 + 31507037 = 31507276
  • 347 + 31506929 = 31507276
  • 389 + 31506887 = 31507276
  • 467 + 31506809 = 31507276
  • 557 + 31506719 = 31507276

Showing the first eight; more decompositions exist.
