Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742884, here are decompositions:

  • 37 + 8742847 = 8742884
  • 67 + 8742817 = 8742884
  • 97 + 8742787 = 8742884
  • 211 + 8742673 = 8742884
  • 307 + 8742577 = 8742884
  • 313 + 8742571 = 8742884
  • 373 + 8742511 = 8742884
  • 421 + 8742463 = 8742884

Showing the first eight; more decompositions exist.
