Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497128, here are decompositions:

11 + 497117 = 497128
17 + 497111 = 497128
59 + 497069 = 497128
131 + 496997 = 497128
179 + 496949 = 497128
227 + 496901 = 497128
239 + 496889 = 497128
251 + 496877 = 497128

Showing the first eight; more decompositions exist.
