Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544144, here are decompositions:

13 + 31544131 = 31544144
67 + 31544077 = 31544144
103 + 31544041 = 31544144
157 + 31543987 = 31544144
241 + 31543903 = 31544144
271 + 31543873 = 31544144
367 + 31543777 = 31544144
421 + 31543723 = 31544144

Showing the first eight; more decompositions exist.
