Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475082, here are decompositions:

11 + 31475071 = 31475082
13 + 31475069 = 31475082
29 + 31475053 = 31475082
53 + 31475029 = 31475082
73 + 31475009 = 31475082
83 + 31474999 = 31475082
101 + 31474981 = 31475082
113 + 31474969 = 31475082

Showing the first eight; more decompositions exist.
