Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548690, here are decompositions:

13 + 31548677 = 31548690
31 + 31548659 = 31548690
37 + 31548653 = 31548690
71 + 31548619 = 31548690
97 + 31548593 = 31548690
113 + 31548577 = 31548690
127 + 31548563 = 31548690
139 + 31548551 = 31548690

Showing the first eight; more decompositions exist.
