Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629442, here are decompositions:

13 + 8629429 = 8629442
109 + 8629333 = 8629442
163 + 8629279 = 8629442
229 + 8629213 = 8629442
271 + 8629171 = 8629442
379 + 8629063 = 8629442
433 + 8629009 = 8629442
439 + 8629003 = 8629442

Showing the first eight; more decompositions exist.
