Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57478, here are decompositions:

11 + 57467 = 57478
89 + 57389 = 57478
131 + 57347 = 57478
149 + 57329 = 57478
191 + 57287 = 57478
227 + 57251 = 57478
257 + 57221 = 57478
347 + 57131 = 57478

Showing the first eight; more decompositions exist.
