Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661132, here are decompositions:

  • 13 + 8661119 = 8661132
  • 43 + 8661089 = 8661132
  • 71 + 8661061 = 8661132
  • 83 + 8661049 = 8661132
  • 89 + 8661043 = 8661132
  • 131 + 8661001 = 8661132
  • 149 + 8660983 = 8661132
  • 163 + 8660969 = 8661132

Showing the first eight; more decompositions exist.
