Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627492, here are decompositions:

  • 101 + 31627391 = 31627492
  • 173 + 31627319 = 31627492
  • 359 + 31627133 = 31627492
  • 401 + 31627091 = 31627492
  • 419 + 31627073 = 31627492
  • 593 + 31626899 = 31627492
  • 599 + 31626893 = 31627492
  • 653 + 31626839 = 31627492

Showing the first eight; more decompositions exist.
