Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625420, here are decompositions:

61 + 8625359 = 8625420
71 + 8625349 = 8625420
103 + 8625317 = 8625420
107 + 8625313 = 8625420
109 + 8625311 = 8625420
131 + 8625289 = 8625420
157 + 8625263 = 8625420
173 + 8625247 = 8625420

Showing the first eight; more decompositions exist.
