Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550734, here are decompositions:

3 + 31550731 = 31550734
11 + 31550723 = 31550734
23 + 31550711 = 31550734
53 + 31550681 = 31550734
107 + 31550627 = 31550734
191 + 31550543 = 31550734
197 + 31550537 = 31550734
263 + 31550471 = 31550734

Showing the first eight; more decompositions exist.
