Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722364, here are decompositions:

3 + 8722361 = 8722364
31 + 8722333 = 8722364
61 + 8722303 = 8722364
67 + 8722297 = 8722364
73 + 8722291 = 8722364
127 + 8722237 = 8722364
193 + 8722171 = 8722364
241 + 8722123 = 8722364

Showing the first eight; more decompositions exist.
