Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463170, here are decompositions:

3 + 31463167 = 31463170
23 + 31463147 = 31463170
47 + 31463123 = 31463170
71 + 31463099 = 31463170
83 + 31463087 = 31463170
107 + 31463063 = 31463170
191 + 31462979 = 31463170
239 + 31462931 = 31463170

Showing the first eight; more decompositions exist.
