Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020580, here are decompositions:

23 + 1020557 = 1020580
89 + 1020491 = 1020580
149 + 1020431 = 1020580
167 + 1020413 = 1020580
173 + 1020407 = 1020580
179 + 1020401 = 1020580
191 + 1020389 = 1020580
227 + 1020353 = 1020580

Showing the first eight; more decompositions exist.
