Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591774, here are decompositions:

3 + 8591771 = 8591774
151 + 8591623 = 8591774
157 + 8591617 = 8591774
181 + 8591593 = 8591774
211 + 8591563 = 8591774
241 + 8591533 = 8591774
307 + 8591467 = 8591774
397 + 8591377 = 8591774

Showing the first eight; more decompositions exist.
