Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671772, here are decompositions:

3 + 8671769 = 8671772
61 + 8671711 = 8671772
103 + 8671669 = 8671772
139 + 8671633 = 8671772
199 + 8671573 = 8671772
223 + 8671549 = 8671772
271 + 8671501 = 8671772
331 + 8671441 = 8671772

Showing the first eight; more decompositions exist.
