Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544066, here are decompositions:

13 + 31544053 = 31544066
79 + 31543987 = 31544066
139 + 31543927 = 31544066
163 + 31543903 = 31544066
193 + 31543873 = 31544066
223 + 31543843 = 31544066
283 + 31543783 = 31544066
397 + 31543669 = 31544066

Showing the first eight; more decompositions exist.
