Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492128, here are decompositions:

61 + 492067 = 492128
67 + 492061 = 492128
151 + 491977 = 492128
229 + 491899 = 492128
271 + 491857 = 492128
277 + 491851 = 492128
331 + 491797 = 492128
397 + 491731 = 492128

Showing the first eight; more decompositions exist.
