Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8602642, here are decompositions:

  • 5 + 8602637 = 8602642
  • 11 + 8602631 = 8602642
  • 131 + 8602511 = 8602642
  • 233 + 8602409 = 8602642
  • 263 + 8602379 = 8602642
  • 431 + 8602211 = 8602642
  • 443 + 8602199 = 8602642
  • 491 + 8602151 = 8602642

Showing the first eight; more decompositions exist.
