Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645394, here are decompositions:

13 + 8645381 = 8645394
41 + 8645353 = 8645394
53 + 8645341 = 8645394
67 + 8645327 = 8645394
101 + 8645293 = 8645394
113 + 8645281 = 8645394
127 + 8645267 = 8645394
137 + 8645257 = 8645394

Showing the first eight; more decompositions exist.
