Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545504, here are decompositions:

  • 5 + 31545499 = 31545504
  • 17 + 31545487 = 31545504
  • 97 + 31545407 = 31545504
  • 103 + 31545401 = 31545504
  • 113 + 31545391 = 31545504
  • 131 + 31545373 = 31545504
  • 173 + 31545331 = 31545504
  • 181 + 31545323 = 31545504

Showing the first eight; more decompositions exist.
