Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724830, here are decompositions:

  • 3 + 8724827 = 8724830
  • 31 + 8724799 = 8724830
  • 43 + 8724787 = 8724830
  • 109 + 8724721 = 8724830
  • 181 + 8724649 = 8724830
  • 199 + 8724631 = 8724830
  • 211 + 8724619 = 8724830
  • 229 + 8724601 = 8724830

Showing the first eight; more decompositions exist.
