Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111636, here are decompositions:

13 + 111623 = 111636
37 + 111599 = 111636
43 + 111593 = 111636
59 + 111577 = 111636
97 + 111539 = 111636
103 + 111533 = 111636
127 + 111509 = 111636
139 + 111497 = 111636

Showing the first eight; more decompositions exist.
