Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551674, here are decompositions:

3 + 31551671 = 31551674
61 + 31551613 = 31551674
97 + 31551577 = 31551674
127 + 31551547 = 31551674
157 + 31551517 = 31551674
223 + 31551451 = 31551674
313 + 31551361 = 31551674
367 + 31551307 = 31551674

Showing the first eight; more decompositions exist.
