Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626144, here are decompositions:

3 + 8626141 = 8626144
5 + 8626139 = 8626144
41 + 8626103 = 8626144
83 + 8626061 = 8626144
101 + 8626043 = 8626144
311 + 8625833 = 8626144
503 + 8625641 = 8626144
557 + 8625587 = 8626144

Showing the first eight; more decompositions exist.
