Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77744, here are decompositions:

13 + 77731 = 77744
31 + 77713 = 77744
97 + 77647 = 77744
103 + 77641 = 77744
127 + 77617 = 77744
157 + 77587 = 77744
181 + 77563 = 77744
193 + 77551 = 77744

Showing the first eight; more decompositions exist.
