Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111642, here are decompositions:

5 + 111637 = 111642
19 + 111623 = 111642
31 + 111611 = 111642
43 + 111599 = 111642
61 + 111581 = 111642
103 + 111539 = 111642
109 + 111533 = 111642
149 + 111493 = 111642

Showing the first eight; more decompositions exist.
