Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009490, here are decompositions:

3 + 1009487 = 1009490
7 + 1009483 = 1009490
73 + 1009417 = 1009490
103 + 1009387 = 1009490
199 + 1009291 = 1009490
283 + 1009207 = 1009490
331 + 1009159 = 1009490
337 + 1009153 = 1009490

Showing the first eight; more decompositions exist.
