Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447074, here are decompositions:

5 + 31447069 = 31447074
31 + 31447043 = 31447074
47 + 31447027 = 31447074
53 + 31447021 = 31447074
73 + 31447001 = 31447074
101 + 31446973 = 31447074
137 + 31446937 = 31447074
157 + 31446917 = 31447074

Showing the first eight; more decompositions exist.
