Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544216, here are decompositions:

3 + 31544213 = 31544216
37 + 31544179 = 31544216
127 + 31544089 = 31544216
139 + 31544077 = 31544216
163 + 31544053 = 31544216
229 + 31543987 = 31544216
313 + 31543903 = 31544216
373 + 31543843 = 31544216

Showing the first eight; more decompositions exist.
