Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500338, here are decompositions:

  • 151 + 31500187 = 31500338
  • 349 + 31499989 = 31500338
  • 439 + 31499899 = 31500338
  • 577 + 31499761 = 31500338
  • 607 + 31499731 = 31500338
  • 739 + 31499599 = 31500338
  • 907 + 31499431 = 31500338
  • 937 + 31499401 = 31500338

Showing the first eight; more decompositions exist.
