Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618706, here are decompositions:

  • 3 + 31618703 = 31618706
  • 13 + 31618693 = 31618706
  • 37 + 31618669 = 31618706
  • 43 + 31618663 = 31618706
  • 73 + 31618633 = 31618706
  • 109 + 31618597 = 31618706
  • 127 + 31618579 = 31618706
  • 139 + 31618567 = 31618706

Showing the first eight; more decompositions exist.
