Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77654, here are decompositions:

  • 7 + 77647 = 77654
  • 13 + 77641 = 77654
  • 37 + 77617 = 77654
  • 43 + 77611 = 77654
  • 67 + 77587 = 77654
  • 97 + 77557 = 77654
  • 103 + 77551 = 77654
  • 127 + 77527 = 77654

Showing the first eight; more decompositions exist.
