Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618282, here are decompositions:

31 + 8618251 = 8618282
61 + 8618221 = 8618282
109 + 8618173 = 8618282
151 + 8618131 = 8618282
163 + 8618119 = 8618282
193 + 8618089 = 8618282
199 + 8618083 = 8618282
223 + 8618059 = 8618282

Showing the first eight; more decompositions exist.
