Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642526, here are decompositions:

  • 7 + 8642519 = 8642526
  • 17 + 8642509 = 8642526
  • 19 + 8642507 = 8642526
  • 37 + 8642489 = 8642526
  • 59 + 8642467 = 8642526
  • 73 + 8642453 = 8642526
  • 97 + 8642429 = 8642526
  • 197 + 8642329 = 8642526

Showing the first eight; more decompositions exist.
