Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546620, here are decompositions:

  • 19 + 31546601 = 31546620
  • 23 + 31546597 = 31546620
  • 29 + 31546591 = 31546620
  • 37 + 31546583 = 31546620
  • 47 + 31546573 = 31546620
  • 67 + 31546553 = 31546620
  • 137 + 31546483 = 31546620
  • 151 + 31546469 = 31546620

Showing the first eight; more decompositions exist.
