Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747412, here are decompositions:

5 + 8747407 = 8747412
31 + 8747381 = 8747412
83 + 8747329 = 8747412
139 + 8747273 = 8747412
151 + 8747261 = 8747412
199 + 8747213 = 8747412
241 + 8747171 = 8747412
293 + 8747119 = 8747412

Showing the first eight; more decompositions exist.
