Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615442, here are decompositions:

19 + 8615423 = 8615442
53 + 8615389 = 8615442
109 + 8615333 = 8615442
163 + 8615279 = 8615442
181 + 8615261 = 8615442
211 + 8615231 = 8615442
223 + 8615219 = 8615442
281 + 8615161 = 8615442

Showing the first eight; more decompositions exist.
