Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623456, here are decompositions:

47 + 8623409 = 8623456
137 + 8623319 = 8623456
263 + 8623193 = 8623456
353 + 8623103 = 8623456
383 + 8623073 = 8623456
389 + 8623067 = 8623456
419 + 8623037 = 8623456
599 + 8622857 = 8623456

Showing the first eight; more decompositions exist.
