Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742830, here are decompositions:

  • 13 + 8742817 = 8742830
  • 43 + 8742787 = 8742830
  • 157 + 8742673 = 8742830
  • 193 + 8742637 = 8742830
  • 331 + 8742499 = 8742830
  • 337 + 8742493 = 8742830
  • 367 + 8742463 = 8742830
  • 409 + 8742421 = 8742830

Showing the first eight; more decompositions exist.
