Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544146, here are decompositions:

47 + 31544099 = 31544146
89 + 31544057 = 31544146
107 + 31544039 = 31544146
113 + 31544033 = 31544146
149 + 31543997 = 31544146
167 + 31543979 = 31544146
233 + 31543913 = 31544146
239 + 31543907 = 31544146

Showing the first eight; more decompositions exist.
