Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111688, here are decompositions:

29 + 111659 = 111688
47 + 111641 = 111688
89 + 111599 = 111688
107 + 111581 = 111688
149 + 111539 = 111688
167 + 111521 = 111688
179 + 111509 = 111688
191 + 111497 = 111688

Showing the first eight; more decompositions exist.
