Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026650, here are decompositions:

67 + 1026583 = 1026650
73 + 1026577 = 1026650
103 + 1026547 = 1026650
193 + 1026457 = 1026650
211 + 1026439 = 1026650
223 + 1026427 = 1026650
337 + 1026313 = 1026650
397 + 1026253 = 1026650

Showing the first eight; more decompositions exist.
