Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625686, here are decompositions:

37 + 8625649 = 8625686
127 + 8625559 = 8625686
193 + 8625493 = 8625686
337 + 8625349 = 8625686
373 + 8625313 = 8625686
397 + 8625289 = 8625686
439 + 8625247 = 8625686
457 + 8625229 = 8625686

Showing the first eight; more decompositions exist.
