Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639374, here are decompositions:

11 + 8639363 = 8639374
83 + 8639291 = 8639374
101 + 8639273 = 8639374
113 + 8639261 = 8639374
167 + 8639207 = 8639374
197 + 8639177 = 8639374
251 + 8639123 = 8639374
311 + 8639063 = 8639374

Showing the first eight; more decompositions exist.
