Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671020, here are decompositions:

  • 11 + 8671009 = 8671020
  • 13 + 8671007 = 8671020
  • 23 + 8670997 = 8671020
  • 31 + 8670989 = 8671020
  • 73 + 8670947 = 8671020
  • 79 + 8670941 = 8671020
  • 101 + 8670919 = 8671020
  • 151 + 8670869 = 8671020

Showing the first eight; more decompositions exist.
