Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728362, here are decompositions:

31 + 8728331 = 8728362
53 + 8728309 = 8728362
59 + 8728303 = 8728362
73 + 8728289 = 8728362
89 + 8728273 = 8728362
101 + 8728261 = 8728362
151 + 8728211 = 8728362
193 + 8728169 = 8728362

Showing the first eight; more decompositions exist.
