Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111488, here are decompositions:

61 + 111427 = 111488
79 + 111409 = 111488
151 + 111337 = 111488
271 + 111217 = 111488
277 + 111211 = 111488
367 + 111121 = 111488
379 + 111109 = 111488
397 + 111091 = 111488

Showing the first eight; more decompositions exist.
