Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638352, here are decompositions:

3 + 8638349 = 8638352
13 + 8638339 = 8638352
61 + 8638291 = 8638352
139 + 8638213 = 8638352
313 + 8638039 = 8638352
379 + 8637973 = 8638352
409 + 8637943 = 8638352
523 + 8637829 = 8638352

Showing the first eight; more decompositions exist.
