Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024890, here are decompositions:

7 + 1024883 = 1024890
19 + 1024871 = 1024890
37 + 1024853 = 1024890
47 + 1024843 = 1024890
67 + 1024823 = 1024890
107 + 1024783 = 1024890
179 + 1024711 = 1024890
193 + 1024697 = 1024890

Showing the first eight; more decompositions exist.
