Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513034, here are decompositions:

31 + 31513003 = 31513034
37 + 31512997 = 31513034
43 + 31512991 = 31513034
127 + 31512907 = 31513034
193 + 31512841 = 31513034
211 + 31512823 = 31513034
277 + 31512757 = 31513034
331 + 31512703 = 31513034

Showing the first eight; more decompositions exist.
