Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475706, here are decompositions:

23 + 31475683 = 31475706
29 + 31475677 = 31475706
37 + 31475669 = 31475706
83 + 31475623 = 31475706
107 + 31475599 = 31475706
109 + 31475597 = 31475706
127 + 31475579 = 31475706
263 + 31475443 = 31475706

Showing the first eight; more decompositions exist.
