Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551734, here are decompositions:

13 + 31551721 = 31551734
157 + 31551577 = 31551734
283 + 31551451 = 31551734
373 + 31551361 = 31551734
457 + 31551277 = 31551734
547 + 31551187 = 31551734
757 + 31550977 = 31551734
787 + 31550947 = 31551734

Showing the first eight; more decompositions exist.
