Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623644, here are decompositions:

5 + 8623639 = 8623644
23 + 8623621 = 8623644
41 + 8623603 = 8623644
61 + 8623583 = 8623644
97 + 8623547 = 8623644
251 + 8623393 = 8623644
353 + 8623291 = 8623644
383 + 8623261 = 8623644

Showing the first eight; more decompositions exist.
