Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638154, here are decompositions:

3 + 8638151 = 8638154
37 + 8638117 = 8638154
103 + 8638051 = 8638154
163 + 8637991 = 8638154
181 + 8637973 = 8638154
211 + 8637943 = 8638154
307 + 8637847 = 8638154
367 + 8637787 = 8638154

Showing the first eight; more decompositions exist.
