Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613488, here are decompositions:

  • 47 + 31613441 = 31613488
  • 89 + 31613399 = 31613488
  • 131 + 31613357 = 31613488
  • 197 + 31613291 = 31613488
  • 239 + 31613249 = 31613488
  • 317 + 31613171 = 31613488
  • 461 + 31613027 = 31613488
  • 761 + 31612727 = 31613488

Showing the first eight; more decompositions exist.
