Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625942, here are decompositions:

29 + 8625913 = 8625942
41 + 8625901 = 8625942
53 + 8625889 = 8625942
89 + 8625853 = 8625942
109 + 8625833 = 8625942
131 + 8625811 = 8625942
233 + 8625709 = 8625942
293 + 8625649 = 8625942

Showing the first eight; more decompositions exist.
