Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618374, here are decompositions:

47 + 8618327 = 8618374
101 + 8618273 = 8618374
131 + 8618243 = 8618374
137 + 8618237 = 8618374
227 + 8618147 = 8618374
311 + 8618063 = 8618374
353 + 8618021 = 8618374
383 + 8617991 = 8618374

Showing the first eight; more decompositions exist.
