Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542932, here are decompositions:

  • 103 + 31542829 = 31542932
  • 229 + 31542703 = 31542932
  • 373 + 31542559 = 31542932
  • 409 + 31542523 = 31542932
  • 541 + 31542391 = 31542932
  • 769 + 31542163 = 31542932
  • 829 + 31542103 = 31542932
  • 919 + 31542013 = 31542932

Showing the first eight; more decompositions exist.
