Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616442, here are decompositions:

11 + 8616431 = 8616442
71 + 8616371 = 8616442
89 + 8616353 = 8616442
239 + 8616203 = 8616442
269 + 8616173 = 8616442
293 + 8616149 = 8616442
311 + 8616131 = 8616442
353 + 8616089 = 8616442

Showing the first eight; more decompositions exist.
