Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612378, here are decompositions:

31 + 8612347 = 8612378
67 + 8612311 = 8612378
79 + 8612299 = 8612378
157 + 8612221 = 8612378
211 + 8612167 = 8612378
367 + 8612011 = 8612378
409 + 8611969 = 8612378
487 + 8611891 = 8612378

Showing the first eight; more decompositions exist.
