Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661654, here are decompositions:

  • 11 + 8661643 = 8661654
  • 13 + 8661641 = 8661654
  • 31 + 8661623 = 8661654
  • 73 + 8661581 = 8661654
  • 83 + 8661571 = 8661654
  • 97 + 8661557 = 8661654
  • 101 + 8661553 = 8661654
  • 163 + 8661491 = 8661654

Showing the first eight; more decompositions exist.
