Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53128, here are decompositions:

11 + 53117 = 53128
41 + 53087 = 53128
59 + 53069 = 53128
191 + 52937 = 53128
227 + 52901 = 53128
239 + 52889 = 53128
269 + 52859 = 53128
311 + 52817 = 53128

Showing the first eight; more decompositions exist.
