Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724186, here are decompositions:

  • 5 + 8724181 = 8724186
  • 17 + 8724169 = 8724186
  • 43 + 8724143 = 8724186
  • 47 + 8724139 = 8724186
  • 59 + 8724127 = 8724186
  • 113 + 8724073 = 8724186
  • 173 + 8724013 = 8724186
  • 193 + 8723993 = 8724186

Showing the first eight; more decompositions exist.
