Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623628, here are decompositions:

7 + 8623621 = 8623628
109 + 8623519 = 8623628
199 + 8623429 = 8623628
271 + 8623357 = 8623628
337 + 8623291 = 8623628
367 + 8623261 = 8623628
379 + 8623249 = 8623628
487 + 8623141 = 8623628

Showing the first eight; more decompositions exist.
