Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636394, here are decompositions:

5 + 8636389 = 8636394
7 + 8636387 = 8636394
17 + 8636377 = 8636394
47 + 8636347 = 8636394
131 + 8636263 = 8636394
157 + 8636237 = 8636394
227 + 8636167 = 8636394
257 + 8636137 = 8636394

Showing the first eight; more decompositions exist.
