Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544000, here are decompositions:

3 + 31543997 = 31544000
13 + 31543987 = 31544000
73 + 31543927 = 31544000
97 + 31543903 = 31544000
127 + 31543873 = 31544000
157 + 31543843 = 31544000
223 + 31543777 = 31544000
277 + 31543723 = 31544000

Showing the first eight; more decompositions exist.
