Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668372, here are decompositions:

3 + 8668369 = 8668372
5 + 8668367 = 8668372
23 + 8668349 = 8668372
71 + 8668301 = 8668372
179 + 8668193 = 8668372
239 + 8668133 = 8668372
311 + 8668061 = 8668372
443 + 8667929 = 8668372

Showing the first eight; more decompositions exist.
