Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625142, here are decompositions:

11 + 8625131 = 8625142
23 + 8625119 = 8625142
59 + 8625083 = 8625142
83 + 8625059 = 8625142
89 + 8625053 = 8625142
131 + 8625011 = 8625142
269 + 8624873 = 8625142
389 + 8624753 = 8625142

Showing the first eight; more decompositions exist.
