Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618240, here are decompositions:

3 + 8618237 = 8618240
19 + 8618221 = 8618240
67 + 8618173 = 8618240
109 + 8618131 = 8618240
151 + 8618089 = 8618240
157 + 8618083 = 8618240
181 + 8618059 = 8618240
193 + 8618047 = 8618240

Showing the first eight; more decompositions exist.
