Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598750, here are decompositions:

  • 67 + 31598683 = 31598750
  • 103 + 31598647 = 31598750
  • 229 + 31598521 = 31598750
  • 331 + 31598419 = 31598750
  • 349 + 31598401 = 31598750
  • 373 + 31598377 = 31598750
  • 397 + 31598353 = 31598750
  • 523 + 31598227 = 31598750

Showing the first eight; more decompositions exist.
