Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545844, here are decompositions:

  • 3 + 31545841 = 31545844
  • 101 + 31545743 = 31545844
  • 107 + 31545737 = 31545844
  • 131 + 31545713 = 31545844
  • 233 + 31545611 = 31545844
  • 443 + 31545401 = 31545844
  • 521 + 31545323 = 31545844
  • 557 + 31545287 = 31545844

Showing the first eight; more decompositions exist.
