Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476260, here are decompositions:

  • 73 + 31476187 = 31476260
  • 103 + 31476157 = 31476260
  • 163 + 31476097 = 31476260
  • 229 + 31476031 = 31476260
  • 307 + 31475953 = 31476260
  • 331 + 31475929 = 31476260
  • 349 + 31475911 = 31476260
  • 433 + 31475827 = 31476260

Showing the first eight; more decompositions exist.
