Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490064, here are decompositions:

7 + 490057 = 490064
31 + 490033 = 490064
61 + 490003 = 490064
103 + 489961 = 490064
151 + 489913 = 490064
163 + 489901 = 490064
193 + 489871 = 490064
241 + 489823 = 490064

Showing the first eight; more decompositions exist.
