Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77750, here are decompositions:

3 + 77747 = 77750
7 + 77743 = 77750
19 + 77731 = 77750
31 + 77719 = 77750
37 + 77713 = 77750
61 + 77689 = 77750
103 + 77647 = 77750
109 + 77641 = 77750

Showing the first eight; more decompositions exist.
