Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750644, here are decompositions:

3 + 8750641 = 8750644
5 + 8750639 = 8750644
53 + 8750591 = 8750644
113 + 8750531 = 8750644
173 + 8750471 = 8750644
191 + 8750453 = 8750644
197 + 8750447 = 8750644
257 + 8750387 = 8750644

Showing the first eight; more decompositions exist.
