Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614500, here are decompositions:

  • 7 + 31614493 = 31614500
  • 157 + 31614343 = 31614500
  • 223 + 31614277 = 31614500
  • 271 + 31614229 = 31614500
  • 283 + 31614217 = 31614500
  • 367 + 31614133 = 31614500
  • 409 + 31614091 = 31614500
  • 439 + 31614061 = 31614500

Showing the first eight; more decompositions exist.
