Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618262, here are decompositions:

5 + 8618257 = 8618262
11 + 8618251 = 8618262
19 + 8618243 = 8618262
41 + 8618221 = 8618262
89 + 8618173 = 8618262
113 + 8618149 = 8618262
131 + 8618131 = 8618262
173 + 8618089 = 8618262

Showing the first eight; more decompositions exist.
