Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618364, here are decompositions:

37 + 8618327 = 8618364
47 + 8618317 = 8618364
67 + 8618297 = 8618364
71 + 8618293 = 8618364
107 + 8618257 = 8618364
113 + 8618251 = 8618364
127 + 8618237 = 8618364
151 + 8618213 = 8618364

Showing the first eight; more decompositions exist.
