Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022378, here are decompositions:

37 + 1022341 = 1022378
127 + 1022251 = 1022378
199 + 1022179 = 1022378
211 + 1022167 = 1022378
241 + 1022137 = 1022378
307 + 1022071 = 1022378
367 + 1022011 = 1022378
499 + 1021879 = 1022378

Showing the first eight; more decompositions exist.
