Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623658, here are decompositions:

7 + 8623651 = 8623658
19 + 8623639 = 8623658
37 + 8623621 = 8623658
79 + 8623579 = 8623658
139 + 8623519 = 8623658
229 + 8623429 = 8623658
367 + 8623291 = 8623658
397 + 8623261 = 8623658

Showing the first eight; more decompositions exist.
