Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497546, here are decompositions:

  • 5 + 31497541 = 31497546
  • 19 + 31497527 = 31497546
  • 23 + 31497523 = 31497546
  • 79 + 31497467 = 31497546
  • 83 + 31497463 = 31497546
  • 97 + 31497449 = 31497546
  • 103 + 31497443 = 31497546
  • 137 + 31497409 = 31497546

Showing the first eight; more decompositions exist.
