Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625158, here are decompositions:

37 + 8625121 = 8625158
67 + 8625091 = 8625158
151 + 8625007 = 8625158
229 + 8624929 = 8625158
271 + 8624887 = 8625158
277 + 8624881 = 8625158
337 + 8624821 = 8625158
541 + 8624617 = 8625158

Showing the first eight; more decompositions exist.
