Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72776, here are decompositions:

13 + 72763 = 72776
37 + 72739 = 72776
43 + 72733 = 72776
97 + 72679 = 72776
103 + 72673 = 72776
127 + 72649 = 72776
163 + 72613 = 72776
199 + 72577 = 72776

Showing the first eight; more decompositions exist.
