Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544158, here are decompositions:

5 + 31544153 = 31544158
59 + 31544099 = 31544158
101 + 31544057 = 31544158
137 + 31544021 = 31544158
167 + 31543991 = 31544158
179 + 31543979 = 31544158
197 + 31543961 = 31544158
251 + 31543907 = 31544158

Showing the first eight; more decompositions exist.
