Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648770, here are decompositions:

  • 23 + 8648747 = 8648770
  • 29 + 8648741 = 8648770
  • 41 + 8648729 = 8648770
  • 83 + 8648687 = 8648770
  • 227 + 8648543 = 8648770
  • 233 + 8648537 = 8648770
  • 239 + 8648531 = 8648770
  • 257 + 8648513 = 8648770

Showing the first eight; more decompositions exist.
