Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621314, here are decompositions:

5 + 8621309 = 8621314
71 + 8621243 = 8621314
101 + 8621213 = 8621314
113 + 8621201 = 8621314
131 + 8621183 = 8621314
167 + 8621147 = 8621314
227 + 8621087 = 8621314
263 + 8621051 = 8621314

Showing the first eight; more decompositions exist.
