Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641274, here are decompositions:

43 + 8641231 = 8641274
127 + 8641147 = 8641274
181 + 8641093 = 8641274
211 + 8641063 = 8641274
307 + 8640967 = 8641274
457 + 8640817 = 8641274
487 + 8640787 = 8641274
541 + 8640733 = 8641274

Showing the first eight; more decompositions exist.
