Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625404, here are decompositions:

61 + 8625343 = 8625404
103 + 8625301 = 8625404
157 + 8625247 = 8625404
283 + 8625121 = 8625404
313 + 8625091 = 8625404
331 + 8625073 = 8625404
397 + 8625007 = 8625404
523 + 8624881 = 8625404

Showing the first eight; more decompositions exist.
