Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72774, here are decompositions:

7 + 72767 = 72774
11 + 72763 = 72774
41 + 72733 = 72774
47 + 72727 = 72774
67 + 72707 = 72774
73 + 72701 = 72774
101 + 72673 = 72774
103 + 72671 = 72774

Showing the first eight; more decompositions exist.
