Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496580, here are decompositions:

  • 7 + 31496573 = 31496580
  • 13 + 31496567 = 31496580
  • 29 + 31496551 = 31496580
  • 41 + 31496539 = 31496580
  • 43 + 31496537 = 31496580
  • 61 + 31496519 = 31496580
  • 131 + 31496449 = 31496580
  • 139 + 31496441 = 31496580

Showing the first eight; more decompositions exist.
