Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490368, here are decompositions:

29 + 490339 = 490368
59 + 490309 = 490368
97 + 490271 = 490368
101 + 490267 = 490368
127 + 490241 = 490368
167 + 490201 = 490368
199 + 490169 = 490368
251 + 490117 = 490368

Showing the first eight; more decompositions exist.
