Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022426, here are decompositions:

37 + 1022389 = 1022426
43 + 1022383 = 1022426
313 + 1022113 = 1022426
367 + 1022059 = 1022426
373 + 1022053 = 1022426
409 + 1022017 = 1022426
463 + 1021963 = 1022426
547 + 1021879 = 1022426

Showing the first eight; more decompositions exist.
