Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022260, here are decompositions:

11 + 1022249 = 1022260
17 + 1022243 = 1022260
23 + 1022237 = 1022260
59 + 1022201 = 1022260
131 + 1022129 = 1022260
137 + 1022123 = 1022260
227 + 1022033 = 1022260
353 + 1021907 = 1022260

Showing the first eight; more decompositions exist.
