Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615800, here are decompositions:

  • 29 + 8615771 = 8615800
  • 107 + 8615693 = 8615800
  • 233 + 8615567 = 8615800
  • 257 + 8615543 = 8615800
  • 293 + 8615507 = 8615800
  • 467 + 8615333 = 8615800
  • 521 + 8615279 = 8615800
  • 563 + 8615237 = 8615800

Showing the first eight; more decompositions exist.
