Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661198, here are decompositions:

  • 5 + 8661193 = 8661198
  • 17 + 8661181 = 8661198
  • 37 + 8661161 = 8661198
  • 61 + 8661137 = 8661198
  • 79 + 8661119 = 8661198
  • 109 + 8661089 = 8661198
  • 137 + 8661061 = 8661198
  • 149 + 8661049 = 8661198

Showing the first eight; more decompositions exist.
