Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619248, here are decompositions:

7 + 8619241 = 8619248
19 + 8619229 = 8619248
37 + 8619211 = 8619248
97 + 8619151 = 8619248
151 + 8619097 = 8619248
181 + 8619067 = 8619248
331 + 8618917 = 8619248
397 + 8618851 = 8619248

Showing the first eight; more decompositions exist.
