Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12830, here are decompositions:

  • 7 + 12823 = 12830
  • 31 + 12799 = 12830
  • 67 + 12763 = 12830
  • 73 + 12757 = 12830
  • 109 + 12721 = 12830
  • 127 + 12703 = 12830
  • 193 + 12637 = 12830
  • 211 + 12619 = 12830

Showing the first eight; more decompositions exist.
