Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639254, here are decompositions:

3 + 8639251 = 8639254
5 + 8639249 = 8639254
47 + 8639207 = 8639254
83 + 8639171 = 8639254
101 + 8639153 = 8639254
131 + 8639123 = 8639254
191 + 8639063 = 8639254
227 + 8639027 = 8639254

Showing the first eight; more decompositions exist.
