Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678372, here are decompositions:

13 + 8678359 = 8678372
19 + 8678353 = 8678372
61 + 8678311 = 8678372
193 + 8678179 = 8678372
211 + 8678161 = 8678372
223 + 8678149 = 8678372
379 + 8677993 = 8678372
421 + 8677951 = 8678372

Showing the first eight; more decompositions exist.
