Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447084, here are decompositions:

3 + 31447081 = 31447084
5 + 31447079 = 31447084
41 + 31447043 = 31447084
83 + 31447001 = 31447084
101 + 31446983 = 31447084
131 + 31446953 = 31447084
167 + 31446917 = 31447084
191 + 31446893 = 31447084

Showing the first eight; more decompositions exist.
