Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619428, here are decompositions:

7 + 8619421 = 8619428
31 + 8619397 = 8619428
199 + 8619229 = 8619428
229 + 8619199 = 8619428
271 + 8619157 = 8619428
277 + 8619151 = 8619428
331 + 8619097 = 8619428
397 + 8619031 = 8619428

Showing the first eight; more decompositions exist.
