Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642260, here are decompositions:

23 + 8642237 = 8642260
71 + 8642189 = 8642260
101 + 8642159 = 8642260
113 + 8642147 = 8642260
149 + 8642111 = 8642260
197 + 8642063 = 8642260
227 + 8642033 = 8642260
233 + 8642027 = 8642260

Showing the first eight; more decompositions exist.
