Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625574, here are decompositions:

47 + 8625527 = 8625574
53 + 8625521 = 8625574
107 + 8625467 = 8625574
257 + 8625317 = 8625574
263 + 8625311 = 8625574
311 + 8625263 = 8625574
383 + 8625191 = 8625574
401 + 8625173 = 8625574

Showing the first eight; more decompositions exist.
