Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615198, here are decompositions:

37 + 8615161 = 8615198
61 + 8615137 = 8615198
181 + 8615017 = 8615198
211 + 8614987 = 8615198
331 + 8614867 = 8615198
349 + 8614849 = 8615198
367 + 8614831 = 8615198
409 + 8614789 = 8615198

Showing the first eight; more decompositions exist.
