Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717380, here are decompositions:

107 + 8717273 = 8717380
167 + 8717213 = 8717380
179 + 8717201 = 8717380
257 + 8717123 = 8717380
263 + 8717117 = 8717380
359 + 8717021 = 8717380
383 + 8716997 = 8717380
461 + 8716919 = 8717380

Showing the first eight; more decompositions exist.
