Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623736, here are decompositions:

7 + 8623729 = 8623736
19 + 8623717 = 8623736
97 + 8623639 = 8623736
157 + 8623579 = 8623736
307 + 8623429 = 8623736
313 + 8623423 = 8623736
379 + 8623357 = 8623736
397 + 8623339 = 8623736

Showing the first eight; more decompositions exist.
