Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77574, here are decompositions:

5 + 77569 = 77574
11 + 77563 = 77574
17 + 77557 = 77574
23 + 77551 = 77574
31 + 77543 = 77574
47 + 77527 = 77574
53 + 77521 = 77574
61 + 77513 = 77574

Showing the first eight; more decompositions exist.
