Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727774, here are decompositions:

7 + 8727767 = 8727774
17 + 8727757 = 8727774
43 + 8727731 = 8727774
47 + 8727727 = 8727774
73 + 8727701 = 8727774
101 + 8727673 = 8727774
131 + 8727643 = 8727774
151 + 8727623 = 8727774

Showing the first eight; more decompositions exist.
