Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022890, here are decompositions:

41 + 1022849 = 1022890
47 + 1022843 = 1022890
53 + 1022837 = 1022890
251 + 1022639 = 1022890
257 + 1022633 = 1022890
317 + 1022573 = 1022890
359 + 1022531 = 1022890
383 + 1022507 = 1022890

Showing the first eight; more decompositions exist.
