Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615270, here are decompositions:

3 + 8615267 = 8615270
73 + 8615197 = 8615270
109 + 8615161 = 8615270
283 + 8614987 = 8615270
331 + 8614939 = 8615270
397 + 8614873 = 8615270
421 + 8614849 = 8615270
439 + 8614831 = 8615270

Showing the first eight; more decompositions exist.
