Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112290, here are decompositions:

11 + 112279 = 112290
29 + 112261 = 112290
37 + 112253 = 112290
41 + 112249 = 112290
43 + 112247 = 112290
53 + 112237 = 112290
67 + 112223 = 112290
83 + 112207 = 112290

Showing the first eight; more decompositions exist.
