Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615252, here are decompositions:

103 + 8615149 = 8615252
313 + 8614939 = 8615252
379 + 8614873 = 8615252
421 + 8614831 = 8615252
463 + 8614789 = 8615252
523 + 8614729 = 8615252
571 + 8614681 = 8615252
601 + 8614651 = 8615252

Showing the first eight; more decompositions exist.
