Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623430, here are decompositions:

7 + 8623423 = 8623430
37 + 8623393 = 8623430
73 + 8623357 = 8623430
139 + 8623291 = 8623430
181 + 8623249 = 8623430
307 + 8623123 = 8623430
349 + 8623081 = 8623430
379 + 8623051 = 8623430

Showing the first eight; more decompositions exist.
