Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544196, here are decompositions:

7 + 31544189 = 31544196
17 + 31544179 = 31544196
29 + 31544167 = 31544196
43 + 31544153 = 31544196
97 + 31544099 = 31544196
107 + 31544089 = 31544196
139 + 31544057 = 31544196
157 + 31544039 = 31544196

Showing the first eight; more decompositions exist.
