Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544202, here are decompositions:

13 + 31544189 = 31544202
23 + 31544179 = 31544202
31 + 31544171 = 31544202
71 + 31544131 = 31544202
103 + 31544099 = 31544202
113 + 31544089 = 31544202
149 + 31544053 = 31544202
163 + 31544039 = 31544202

Showing the first eight; more decompositions exist.
