Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693478, here are decompositions:

11 + 8693467 = 8693478
19 + 8693459 = 8693478
37 + 8693441 = 8693478
71 + 8693407 = 8693478
97 + 8693381 = 8693478
109 + 8693369 = 8693478
139 + 8693339 = 8693478
151 + 8693327 = 8693478

Showing the first eight; more decompositions exist.
