Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022564, here are decompositions:

61 + 1022503 = 1022564
73 + 1022491 = 1022564
97 + 1022467 = 1022564
181 + 1022383 = 1022564
223 + 1022341 = 1022564
313 + 1022251 = 1022564
373 + 1022191 = 1022564
397 + 1022167 = 1022564

Showing the first eight; more decompositions exist.
