Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681478, here are decompositions:

5 + 8681473 = 8681478
11 + 8681467 = 8681478
31 + 8681447 = 8681478
101 + 8681377 = 8681478
109 + 8681369 = 8681478
137 + 8681341 = 8681478
167 + 8681311 = 8681478
191 + 8681287 = 8681478

Showing the first eight; more decompositions exist.
