Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562680, here are decompositions:

3 + 31562677 = 31562680
53 + 31562627 = 31562680
59 + 31562621 = 31562680
113 + 31562567 = 31562680
137 + 31562543 = 31562680
179 + 31562501 = 31562680
197 + 31562483 = 31562680
239 + 31562441 = 31562680

Showing the first eight; more decompositions exist.
