Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111518, here are decompositions:

31 + 111487 = 111518
79 + 111439 = 111518
109 + 111409 = 111518
181 + 111337 = 111518
307 + 111211 = 111518
331 + 111187 = 111518
397 + 111121 = 111518
409 + 111109 = 111518

Showing the first eight; more decompositions exist.
