Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496620, here are decompositions:

  • 47 + 31496573 = 31496620
  • 53 + 31496567 = 31496620
  • 83 + 31496537 = 31496620
  • 101 + 31496519 = 31496620
  • 131 + 31496489 = 31496620
  • 179 + 31496441 = 31496620
  • 191 + 31496429 = 31496620
  • 251 + 31496369 = 31496620

Showing the first eight; more decompositions exist.
