Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544090, here are decompositions:

13 + 31544077 = 31544090
37 + 31544053 = 31544090
79 + 31544011 = 31544090
103 + 31543987 = 31544090
163 + 31543927 = 31544090
307 + 31543783 = 31544090
313 + 31543777 = 31544090
367 + 31543723 = 31544090

Showing the first eight; more decompositions exist.
