Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111438, here are decompositions:

7 + 111431 = 111438
11 + 111427 = 111438
29 + 111409 = 111438
97 + 111341 = 111438
101 + 111337 = 111438
137 + 111301 = 111438
167 + 111271 = 111438
211 + 111227 = 111438

Showing the first eight; more decompositions exist.
