Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551726, here are decompositions:

5 + 31551721 = 31551726
43 + 31551683 = 31551726
97 + 31551629 = 31551726
113 + 31551613 = 31551726
127 + 31551599 = 31551726
139 + 31551587 = 31551726
149 + 31551577 = 31551726
179 + 31551547 = 31551726

Showing the first eight; more decompositions exist.
