Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30756, here are decompositions:

29 + 30727 = 30756
43 + 30713 = 30756
53 + 30703 = 30756
59 + 30697 = 30756
67 + 30689 = 30756
79 + 30677 = 30756
107 + 30649 = 30756
113 + 30643 = 30756

Showing the first eight; more decompositions exist.
