Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490402, here are decompositions:

89 + 490313 = 490402
131 + 490271 = 490402
179 + 490223 = 490402
233 + 490169 = 490402
251 + 490151 = 490402
281 + 490121 = 490402
383 + 490019 = 490402
401 + 490001 = 490402

Showing the first eight; more decompositions exist.
