Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023580, here are decompositions:

3 + 1023577 = 1023580
23 + 1023557 = 1023580
29 + 1023551 = 1023580
59 + 1023521 = 1023580
113 + 1023467 = 1023580
167 + 1023413 = 1023580
191 + 1023389 = 1023580
227 + 1023353 = 1023580

Showing the first eight; more decompositions exist.
