Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635972, here are decompositions:

  • 3 + 8635969 = 8635972
  • 5 + 8635967 = 8635972
  • 53 + 8635919 = 8635972
  • 89 + 8635883 = 8635972
  • 419 + 8635553 = 8635972
  • 503 + 8635469 = 8635972
  • 563 + 8635409 = 8635972
  • 659 + 8635313 = 8635972

Showing the first eight; more decompositions exist.
