Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641774, here are decompositions:

41 + 8641733 = 8641774
101 + 8641673 = 8641774
131 + 8641643 = 8641774
227 + 8641547 = 8641774
233 + 8641541 = 8641774
257 + 8641517 = 8641774
353 + 8641421 = 8641774
443 + 8641331 = 8641774

Showing the first eight; more decompositions exist.
