Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550726, here are decompositions:

3 + 31550723 = 31550726
127 + 31550599 = 31550726
139 + 31550587 = 31550726
157 + 31550569 = 31550726
373 + 31550353 = 31550726
397 + 31550329 = 31550726
439 + 31550287 = 31550726
547 + 31550179 = 31550726

Showing the first eight; more decompositions exist.
