Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536600, here are decompositions:

  • 61 + 31536539 = 31536600
  • 71 + 31536529 = 31536600
  • 79 + 31536521 = 31536600
  • 101 + 31536499 = 31536600
  • 197 + 31536403 = 31536600
  • 239 + 31536361 = 31536600
  • 241 + 31536359 = 31536600
  • 307 + 31536293 = 31536600

Showing the first eight; more decompositions exist.
