Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488290, here are decompositions:

3 + 488287 = 488290
29 + 488261 = 488290
41 + 488249 = 488290
59 + 488231 = 488290
83 + 488207 = 488290
137 + 488153 = 488290
233 + 488057 = 488290
239 + 488051 = 488290

Showing the first eight; more decompositions exist.
