Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021556, here are decompositions:

73 + 1021483 = 1021556
127 + 1021429 = 1021556
139 + 1021417 = 1021556
223 + 1021333 = 1021556
229 + 1021327 = 1021556
313 + 1021243 = 1021556
373 + 1021183 = 1021556
397 + 1021159 = 1021556

Showing the first eight; more decompositions exist.
