Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002490, here are decompositions:

3 + 1002487 = 1002490
23 + 1002467 = 1002490
113 + 1002377 = 1002490
131 + 1002359 = 1002490
149 + 1002341 = 1002490
191 + 1002299 = 1002490
227 + 1002263 = 1002490
233 + 1002257 = 1002490

Showing the first eight; more decompositions exist.
