Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048390, here are decompositions:

3 + 1048387 = 1048390
23 + 1048367 = 1048390
29 + 1048361 = 1048390
47 + 1048343 = 1048390
173 + 1048217 = 1048390
197 + 1048193 = 1048390
251 + 1048139 = 1048390
263 + 1048127 = 1048390

Showing the first eight; more decompositions exist.
