Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111690, here are decompositions:

23 + 111667 = 111690
31 + 111659 = 111690
37 + 111653 = 111690
53 + 111637 = 111690
67 + 111623 = 111690
79 + 111611 = 111690
97 + 111593 = 111690
109 + 111581 = 111690

Showing the first eight; more decompositions exist.
