Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655128, here are decompositions:

  • 211 + 8654917 = 8655128
  • 367 + 8654761 = 8655128
  • 379 + 8654749 = 8655128
  • 439 + 8654689 = 8655128
  • 487 + 8654641 = 8655128
  • 607 + 8654521 = 8655128
  • 661 + 8654467 = 8655128
  • 739 + 8654389 = 8655128

Showing the first eight; more decompositions exist.
