Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548580, here are decompositions:

3 + 31548577 = 31548580
17 + 31548563 = 31548580
29 + 31548551 = 31548580
47 + 31548533 = 31548580
53 + 31548527 = 31548580
59 + 31548521 = 31548580
113 + 31548467 = 31548580
137 + 31548443 = 31548580

Showing the first eight; more decompositions exist.
