Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638292, here are decompositions:

  • 73 + 8638219 = 8638292
  • 79 + 8638213 = 8638292
  • 109 + 8638183 = 8638292
  • 241 + 8638051 = 8638292
  • 349 + 8637943 = 8638292
  • 463 + 8637829 = 8638292
  • 673 + 8637619 = 8638292
  • 769 + 8637523 = 8638292

Showing the first eight; more decompositions exist.
