Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655242, here are decompositions:

  • 31 + 8655211 = 8655242
  • 139 + 8655103 = 8655242
  • 283 + 8654959 = 8655242
  • 433 + 8654809 = 8655242
  • 439 + 8654803 = 8655242
  • 601 + 8654641 = 8655242
  • 811 + 8654431 = 8655242
  • 853 + 8654389 = 8655242

Showing the first eight; more decompositions exist.
