Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638374, here are decompositions:

37 + 8638337 = 8638374
47 + 8638327 = 8638374
83 + 8638291 = 8638374
97 + 8638277 = 8638374
127 + 8638247 = 8638374
137 + 8638237 = 8638374
167 + 8638207 = 8638374
191 + 8638183 = 8638374

Showing the first eight; more decompositions exist.
