Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005390, here are decompositions:

17 + 1005373 = 1005390
19 + 1005371 = 1005390
31 + 1005359 = 1005390
41 + 1005349 = 1005390
59 + 1005331 = 1005390
73 + 1005317 = 1005390
97 + 1005293 = 1005390
103 + 1005287 = 1005390

Showing the first eight; more decompositions exist.
