Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111778, here are decompositions:

5 + 111773 = 111778
11 + 111767 = 111778
47 + 111731 = 111778
137 + 111641 = 111778
167 + 111611 = 111778
179 + 111599 = 111778
197 + 111581 = 111778
239 + 111539 = 111778

Showing the first eight; more decompositions exist.
