Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638232, here are decompositions:

3 + 8638229 = 8638232
13 + 8638219 = 8638232
19 + 8638213 = 8638232
181 + 8638051 = 8638232
193 + 8638039 = 8638232
199 + 8638033 = 8638232
241 + 8637991 = 8638232
613 + 8637619 = 8638232

Showing the first eight; more decompositions exist.
