Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522554, here are decompositions:

  • 5 + 31522549 = 31522554
  • 13 + 31522541 = 31522554
  • 31 + 31522523 = 31522554
  • 61 + 31522493 = 31522554
  • 103 + 31522451 = 31522554
  • 113 + 31522441 = 31522554
  • 181 + 31522373 = 31522554
  • 191 + 31522363 = 31522554

Showing the first eight; more decompositions exist.
