Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111678, here are decompositions:

11 + 111667 = 111678
19 + 111659 = 111678
37 + 111641 = 111678
41 + 111637 = 111678
67 + 111611 = 111678
79 + 111599 = 111678
97 + 111581 = 111678
101 + 111577 = 111678

Showing the first eight; more decompositions exist.
