Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628372, here are decompositions:

13 + 8628359 = 8628372
19 + 8628353 = 8628372
23 + 8628349 = 8628372
79 + 8628293 = 8628372
101 + 8628271 = 8628372
139 + 8628233 = 8628372
191 + 8628181 = 8628372
199 + 8628173 = 8628372

Showing the first eight; more decompositions exist.
