Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642254, here are decompositions:

17 + 8642237 = 8642254
107 + 8642147 = 8642254
113 + 8642141 = 8642254
191 + 8642063 = 8642254
197 + 8642057 = 8642254
227 + 8642027 = 8642254
251 + 8642003 = 8642254
263 + 8641991 = 8642254

Showing the first eight; more decompositions exist.
