Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476520, here are decompositions:

  • 3 + 31476517 = 31476520
  • 11 + 31476509 = 31476520
  • 59 + 31476461 = 31476520
  • 71 + 31476449 = 31476520
  • 83 + 31476437 = 31476520
  • 107 + 31476413 = 31476520
  • 137 + 31476383 = 31476520
  • 149 + 31476371 = 31476520

Showing the first eight; more decompositions exist.
