Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022430, here are decompositions:

41 + 1022389 = 1022430
43 + 1022387 = 1022430
47 + 1022383 = 1022430
53 + 1022377 = 1022430
89 + 1022341 = 1022430
127 + 1022303 = 1022430
139 + 1022291 = 1022430
179 + 1022251 = 1022430

Showing the first eight; more decompositions exist.
