Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020550, here are decompositions:

59 + 1020491 = 1020550
131 + 1020419 = 1020550
137 + 1020413 = 1020550
149 + 1020401 = 1020550
197 + 1020353 = 1020550
257 + 1020293 = 1020550
281 + 1020269 = 1020550
317 + 1020233 = 1020550

Showing the first eight; more decompositions exist.
