Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536576, here are decompositions:

  • 37 + 31536539 = 31536576
  • 47 + 31536529 = 31536576
  • 173 + 31536403 = 31536576
  • 179 + 31536397 = 31536576
  • 193 + 31536383 = 31536576
  • 223 + 31536353 = 31536576
  • 229 + 31536347 = 31536576
  • 263 + 31536313 = 31536576

Showing the first eight; more decompositions exist.
