Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617144, here are decompositions:

47 + 8617097 = 8617144
71 + 8617073 = 8617144
197 + 8616947 = 8617144
227 + 8616917 = 8617144
233 + 8616911 = 8617144
257 + 8616887 = 8617144
311 + 8616833 = 8617144
317 + 8616827 = 8617144

Showing the first eight; more decompositions exist.
