Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77746, here are decompositions:

3 + 77743 = 77746
23 + 77723 = 77746
47 + 77699 = 77746
59 + 77687 = 77746
173 + 77573 = 77746
197 + 77549 = 77746
233 + 77513 = 77746
257 + 77489 = 77746

Showing the first eight; more decompositions exist.
