Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492428, here are decompositions:

7 + 492421 = 492428
19 + 492409 = 492428
31 + 492397 = 492428
109 + 492319 = 492428
367 + 492061 = 492428
421 + 492007 = 492428
571 + 491857 = 492428
577 + 491851 = 492428

Showing the first eight; more decompositions exist.
