Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625402, here are decompositions:

43 + 8625359 = 8625402
53 + 8625349 = 8625402
59 + 8625343 = 8625402
89 + 8625313 = 8625402
101 + 8625301 = 8625402
113 + 8625289 = 8625402
139 + 8625263 = 8625402
173 + 8625229 = 8625402

Showing the first eight; more decompositions exist.
