Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544006, here are decompositions:

19 + 31543987 = 31544006
79 + 31543927 = 31544006
103 + 31543903 = 31544006
163 + 31543843 = 31544006
223 + 31543783 = 31544006
229 + 31543777 = 31544006
283 + 31543723 = 31544006
337 + 31543669 = 31544006

Showing the first eight; more decompositions exist.
