Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447062, here are decompositions:

19 + 31447043 = 31447062
41 + 31447021 = 31447062
43 + 31447019 = 31447062
61 + 31447001 = 31447062
79 + 31446983 = 31447062
89 + 31446973 = 31447062
109 + 31446953 = 31447062
113 + 31446949 = 31447062

Showing the first eight; more decompositions exist.
