Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560370, here are decompositions:

  • 29 + 31560341 = 31560370
  • 71 + 31560299 = 31560370
  • 131 + 31560239 = 31560370
  • 137 + 31560233 = 31560370
  • 197 + 31560173 = 31560370
  • 263 + 31560107 = 31560370
  • 311 + 31560059 = 31560370
  • 389 + 31559981 = 31560370

Showing the first eight; more decompositions exist.
