Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111278, here are decompositions:

7 + 111271 = 111278
61 + 111217 = 111278
67 + 111211 = 111278
151 + 111127 = 111278
157 + 111121 = 111278
229 + 111049 = 111278
331 + 110947 = 111278
379 + 110899 = 111278

Showing the first eight; more decompositions exist.
