Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661154, here are decompositions:

  • 17 + 8661137 = 8661154
  • 107 + 8661047 = 8661154
  • 167 + 8660987 = 8661154
  • 233 + 8660921 = 8661154
  • 263 + 8660891 = 8661154
  • 401 + 8660753 = 8661154
  • 431 + 8660723 = 8661154
  • 461 + 8660693 = 8661154

Showing the first eight; more decompositions exist.
