Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513632, here are decompositions:

  • 11 + 31513621 = 31513632
  • 19 + 31513613 = 31513632
  • 53 + 31513579 = 31513632
  • 71 + 31513561 = 31513632
  • 229 + 31513403 = 31513632
  • 373 + 31513259 = 31513632
  • 419 + 31513213 = 31513632
  • 431 + 31513201 = 31513632

Showing the first eight; more decompositions exist.
