Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671968, here are decompositions:

31 + 8671937 = 8671968
61 + 8671907 = 8671968
131 + 8671837 = 8671968
157 + 8671811 = 8671968
199 + 8671769 = 8671968
229 + 8671739 = 8671968
257 + 8671711 = 8671968
271 + 8671697 = 8671968

Showing the first eight; more decompositions exist.
