Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637884, here are decompositions:

  • 37 + 8637847 = 8637884
  • 97 + 8637787 = 8637884
  • 433 + 8637451 = 8637884
  • 457 + 8637427 = 8637884
  • 547 + 8637337 = 8637884
  • 631 + 8637253 = 8637884
  • 733 + 8637151 = 8637884
  • 751 + 8637133 = 8637884

Showing the first eight; more decompositions exist.
