Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724810, here are decompositions:

  • 7 + 8724803 = 8724810
  • 11 + 8724799 = 8724810
  • 23 + 8724787 = 8724810
  • 71 + 8724739 = 8724810
  • 89 + 8724721 = 8724810
  • 97 + 8724713 = 8724810
  • 113 + 8724697 = 8724810
  • 167 + 8724643 = 8724810

Showing the first eight; more decompositions exist.
