Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157482, here are decompositions:

5 + 157477 = 157482
53 + 157429 = 157482
71 + 157411 = 157482
89 + 157393 = 157482
131 + 157351 = 157482
179 + 157303 = 157482
191 + 157291 = 157482
211 + 157271 = 157482

Showing the first eight; more decompositions exist.
