Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728382, here are decompositions:

  • 73 + 8728309 = 8728382
  • 79 + 8728303 = 8728382
  • 109 + 8728273 = 8728382
  • 709 + 8727673 = 8728382
  • 739 + 8727643 = 8728382
  • 853 + 8727529 = 8728382
  • 1033 + 8727349 = 8728382
  • 1039 + 8727343 = 8728382

Showing the first eight; more decompositions exist.
