Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615950, here are decompositions:

59 + 8615891 = 8615950
71 + 8615879 = 8615950
179 + 8615771 = 8615950
227 + 8615723 = 8615950
257 + 8615693 = 8615950
293 + 8615657 = 8615950
359 + 8615591 = 8615950
383 + 8615567 = 8615950

Showing the first eight; more decompositions exist.
