Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11778, here are decompositions:

47 + 11731 = 11778
59 + 11719 = 11778
61 + 11717 = 11778
79 + 11699 = 11778
89 + 11689 = 11778
97 + 11681 = 11778
101 + 11677 = 11778
157 + 11621 = 11778

Showing the first eight; more decompositions exist.
