Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490222, here are decompositions:

53 + 490169 = 490222
71 + 490151 = 490222
101 + 490121 = 490222
191 + 490031 = 490222
233 + 489989 = 490222
263 + 489959 = 490222
281 + 489941 = 490222
311 + 489911 = 490222

Showing the first eight; more decompositions exist.
