Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022438, here are decompositions:

61 + 1022377 = 1022438
97 + 1022341 = 1022438
229 + 1022209 = 1022438
271 + 1022167 = 1022438
367 + 1022071 = 1022438
379 + 1022059 = 1022438
421 + 1022017 = 1022438
541 + 1021897 = 1022438

Showing the first eight; more decompositions exist.
