Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77636, here are decompositions:

19 + 77617 = 77636
67 + 77569 = 77636
73 + 77563 = 77636
79 + 77557 = 77636
109 + 77527 = 77636
127 + 77509 = 77636
157 + 77479 = 77636
277 + 77359 = 77636

Showing the first eight; more decompositions exist.
