Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627142, here are decompositions:

23 + 8627119 = 8627142
31 + 8627111 = 8627142
61 + 8627081 = 8627142
109 + 8627033 = 8627142
113 + 8627029 = 8627142
239 + 8626903 = 8627142
241 + 8626901 = 8627142
281 + 8626861 = 8627142

Showing the first eight; more decompositions exist.
