Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627942, here are decompositions:

3 + 8627939 = 8627942
31 + 8627911 = 8627942
109 + 8627833 = 8627942
229 + 8627713 = 8627942
241 + 8627701 = 8627942
331 + 8627611 = 8627942
373 + 8627569 = 8627942
409 + 8627533 = 8627942

Showing the first eight; more decompositions exist.
