Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627242, here are decompositions:

  • 89 + 8627153 = 8627242
  • 101 + 8627141 = 8627242
  • 131 + 8627111 = 8627242
  • 191 + 8627051 = 8627242
  • 401 + 8626841 = 8627242
  • 419 + 8626823 = 8627242
  • 431 + 8626811 = 8627242
  • 479 + 8626763 = 8627242

Showing the first eight; more decompositions exist.
