Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629380, here are decompositions:

31 + 8629349 = 8629380
37 + 8629343 = 8629380
47 + 8629333 = 8629380
83 + 8629297 = 8629380
101 + 8629279 = 8629380
139 + 8629241 = 8629380
167 + 8629213 = 8629380
181 + 8629199 = 8629380

Showing the first eight; more decompositions exist.
