Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639264, here are decompositions:

3 + 8639261 = 8639264
13 + 8639251 = 8639264
37 + 8639227 = 8639264
103 + 8639161 = 8639264
157 + 8639107 = 8639264
313 + 8638951 = 8639264
331 + 8638933 = 8639264
373 + 8638891 = 8639264

Showing the first eight; more decompositions exist.
