Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619380, here are decompositions:

37 + 8619343 = 8619380
139 + 8619241 = 8619380
151 + 8619229 = 8619380
157 + 8619223 = 8619380
181 + 8619199 = 8619380
223 + 8619157 = 8619380
229 + 8619151 = 8619380
283 + 8619097 = 8619380

Showing the first eight; more decompositions exist.
