Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627140, here are decompositions:

29 + 8627111 = 8627140
59 + 8627081 = 8627140
83 + 8627057 = 8627140
89 + 8627051 = 8627140
107 + 8627033 = 8627140
239 + 8626901 = 8627140
293 + 8626847 = 8627140
317 + 8626823 = 8627140

Showing the first eight; more decompositions exist.
