Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551524, here are decompositions:

7 + 31551517 = 31551524
73 + 31551451 = 31551524
163 + 31551361 = 31551524
241 + 31551283 = 31551524
337 + 31551187 = 31551524
373 + 31551151 = 31551524
457 + 31551067 = 31551524
547 + 31550977 = 31551524

Showing the first eight; more decompositions exist.
