Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544170, here are decompositions:

3 + 31544167 = 31544170
17 + 31544153 = 31544170
71 + 31544099 = 31544170
113 + 31544057 = 31544170
131 + 31544039 = 31544170
137 + 31544033 = 31544170
149 + 31544021 = 31544170
173 + 31543997 = 31544170

Showing the first eight; more decompositions exist.
