Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489278, here are decompositions:

37 + 489241 = 489278
61 + 489217 = 489278
151 + 489127 = 489278
277 + 489001 = 489278
331 + 488947 = 489278
457 + 488821 = 489278
487 + 488791 = 489278
499 + 488779 = 489278

Showing the first eight; more decompositions exist.
