Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678186, here are decompositions:

  • 7 + 8678179 = 8678186
  • 37 + 8678149 = 8678186
  • 73 + 8678113 = 8678186
  • 103 + 8678083 = 8678186
  • 157 + 8678029 = 8678186
  • 193 + 8677993 = 8678186
  • 463 + 8677723 = 8678186
  • 523 + 8677663 = 8678186

Showing the first eight; more decompositions exist.
