Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490190, here are decompositions:

7 + 490183 = 490190
31 + 490159 = 490190
73 + 490117 = 490190
79 + 490111 = 490190
157 + 490033 = 490190
229 + 489961 = 490190
277 + 489913 = 490190
367 + 489823 = 490190

Showing the first eight; more decompositions exist.
