Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111420, here are decompositions:

11 + 111409 = 111420
47 + 111373 = 111420
73 + 111347 = 111420
79 + 111341 = 111420
83 + 111337 = 111420
97 + 111323 = 111420
103 + 111317 = 111420
149 + 111271 = 111420

Showing the first eight; more decompositions exist.
