Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625406, here are decompositions:

47 + 8625359 = 8625406
89 + 8625317 = 8625406
173 + 8625233 = 8625406
233 + 8625173 = 8625406
347 + 8625059 = 8625406
353 + 8625053 = 8625406
599 + 8624807 = 8625406
653 + 8624753 = 8625406

Showing the first eight; more decompositions exist.
