Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544156, here are decompositions:

3 + 31544153 = 31544156
67 + 31544089 = 31544156
79 + 31544077 = 31544156
103 + 31544053 = 31544156
229 + 31543927 = 31544156
283 + 31543873 = 31544156
313 + 31543843 = 31544156
373 + 31543783 = 31544156

Showing the first eight; more decompositions exist.
