Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730642, here are decompositions:

  • 13 + 8730629 = 8730642
  • 23 + 8730619 = 8730642
  • 31 + 8730611 = 8730642
  • 59 + 8730583 = 8730642
  • 83 + 8730559 = 8730642
  • 113 + 8730529 = 8730642
  • 131 + 8730511 = 8730642
  • 293 + 8730349 = 8730642

Showing the first eight; more decompositions exist.
