Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638048, here are decompositions:

5 + 8638043 = 8638048
179 + 8637869 = 8638048
227 + 8637821 = 8638048
257 + 8637791 = 8638048
269 + 8637779 = 8638048
347 + 8637701 = 8638048
431 + 8637617 = 8638048
521 + 8637527 = 8638048

Showing the first eight; more decompositions exist.
