Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623904, here are decompositions:

7 + 8623897 = 8623904
61 + 8623843 = 8623904
73 + 8623831 = 8623904
97 + 8623807 = 8623904
103 + 8623801 = 8623904
283 + 8623621 = 8623904
547 + 8623357 = 8623904
613 + 8623291 = 8623904

Showing the first eight; more decompositions exist.
