Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640074, here are decompositions:

61 + 8640013 = 8640074
73 + 8640001 = 8640074
97 + 8639977 = 8640074
151 + 8639923 = 8640074
211 + 8639863 = 8640074
271 + 8639803 = 8640074
277 + 8639797 = 8640074
523 + 8639551 = 8640074

Showing the first eight; more decompositions exist.
