Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047580, here are decompositions:

29 + 1047551 = 1047580
41 + 1047539 = 1047580
47 + 1047533 = 1047580
89 + 1047491 = 1047580
101 + 1047479 = 1047580
113 + 1047467 = 1047580
239 + 1047341 = 1047580
257 + 1047323 = 1047580

Showing the first eight; more decompositions exist.
