Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724722, here are decompositions:

  • 3 + 8724719 = 8724722
  • 73 + 8724649 = 8724722
  • 79 + 8724643 = 8724722
  • 103 + 8724619 = 8724722
  • 163 + 8724559 = 8724722
  • 211 + 8724511 = 8724722
  • 229 + 8724493 = 8724722
  • 421 + 8724301 = 8724722

Showing the first eight; more decompositions exist.
