Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77562, here are decompositions:

5 + 77557 = 77562
11 + 77551 = 77562
13 + 77549 = 77562
19 + 77543 = 77562
41 + 77521 = 77562
53 + 77509 = 77562
71 + 77491 = 77562
73 + 77489 = 77562

Showing the first eight; more decompositions exist.
