Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051490, here are decompositions:

19 + 1051471 = 1051490
31 + 1051459 = 1051490
67 + 1051423 = 1051490
73 + 1051417 = 1051490
157 + 1051333 = 1051490
199 + 1051291 = 1051490
313 + 1051177 = 1051490
337 + 1051153 = 1051490

Showing the first eight; more decompositions exist.
