Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77582, here are decompositions:

13 + 77569 = 77582
19 + 77563 = 77582
31 + 77551 = 77582
61 + 77521 = 77582
73 + 77509 = 77582
103 + 77479 = 77582
151 + 77431 = 77582
163 + 77419 = 77582

Showing the first eight; more decompositions exist.
