Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447122, here are decompositions:

19 + 31447103 = 31447122
23 + 31447099 = 31447122
41 + 31447081 = 31447122
43 + 31447079 = 31447122
53 + 31447069 = 31447122
79 + 31447043 = 31447122
101 + 31447021 = 31447122
103 + 31447019 = 31447122

Showing the first eight; more decompositions exist.
