Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77600, here are decompositions:

13 + 77587 = 77600
31 + 77569 = 77600
37 + 77563 = 77600
43 + 77557 = 77600
73 + 77527 = 77600
79 + 77521 = 77600
109 + 77491 = 77600
181 + 77419 = 77600

Showing the first eight; more decompositions exist.
