Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641506, here are decompositions:

37 + 8641469 = 8641506
53 + 8641453 = 8641506
73 + 8641433 = 8641506
157 + 8641349 = 8641506
179 + 8641327 = 8641506
197 + 8641309 = 8641506
233 + 8641273 = 8641506
257 + 8641249 = 8641506

Showing the first eight; more decompositions exist.
