Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642562, here are decompositions:

  • 29 + 8642533 = 8642562
  • 43 + 8642519 = 8642562
  • 53 + 8642509 = 8642562
  • 73 + 8642489 = 8642562
  • 109 + 8642453 = 8642562
  • 113 + 8642449 = 8642562
  • 179 + 8642383 = 8642562
  • 233 + 8642329 = 8642562

Showing the first eight; more decompositions exist.
