Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111618, here are decompositions:

7 + 111611 = 111618
19 + 111599 = 111618
37 + 111581 = 111618
41 + 111577 = 111618
79 + 111539 = 111618
97 + 111521 = 111618
109 + 111509 = 111618
127 + 111491 = 111618

Showing the first eight; more decompositions exist.
