Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554, here are decompositions:

  • 7 + 31547 = 31554
  • 11 + 31543 = 31554
  • 13 + 31541 = 31554
  • 23 + 31531 = 31554
  • 37 + 31517 = 31554
  • 41 + 31513 = 31554
  • 43 + 31511 = 31554
  • 73 + 31481 = 31554

Showing the first eight; more decompositions exist.
