Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526282, here are decompositions:

  • 43 + 31526239 = 31526282
  • 61 + 31526221 = 31526282
  • 199 + 31526083 = 31526282
  • 331 + 31525951 = 31526282
  • 373 + 31525909 = 31526282
  • 379 + 31525903 = 31526282
  • 433 + 31525849 = 31526282
  • 499 + 31525783 = 31526282

Showing the first eight; more decompositions exist.
