Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537666, here are decompositions:

107 + 31537559 = 31537666
197 + 31537469 = 31537666
233 + 31537433 = 31537666
257 + 31537409 = 31537666
353 + 31537313 = 31537666
359 + 31537307 = 31537666
443 + 31537223 = 31537666
569 + 31537097 = 31537666

Showing the first eight; more decompositions exist.
