Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490154, here are decompositions:

3 + 490151 = 490154
37 + 490117 = 490154
43 + 490111 = 490154
97 + 490057 = 490154
151 + 490003 = 490154
193 + 489961 = 490154
211 + 489943 = 490154
241 + 489913 = 490154

Showing the first eight; more decompositions exist.
