Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489218, here are decompositions:

61 + 489157 = 489218
109 + 489109 = 489218
157 + 489061 = 489218
199 + 489019 = 489218
271 + 488947 = 489218
397 + 488821 = 489218
421 + 488797 = 489218
439 + 488779 = 489218

Showing the first eight; more decompositions exist.
