Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447110, here are decompositions:

7 + 31447103 = 31447110
11 + 31447099 = 31447110
29 + 31447081 = 31447110
31 + 31447079 = 31447110
41 + 31447069 = 31447110
67 + 31447043 = 31447110
83 + 31447027 = 31447110
89 + 31447021 = 31447110

Showing the first eight; more decompositions exist.
