Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672788, here are decompositions:

101 + 8672687 = 8672788
149 + 8672639 = 8672788
167 + 8672621 = 8672788
191 + 8672597 = 8672788
227 + 8672561 = 8672788
269 + 8672519 = 8672788
317 + 8672471 = 8672788
347 + 8672441 = 8672788

Showing the first eight; more decompositions exist.
