Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546790, here are decompositions:

31 + 31546759 = 31546790
73 + 31546717 = 31546790
127 + 31546663 = 31546790
157 + 31546633 = 31546790
193 + 31546597 = 31546790
199 + 31546591 = 31546790
307 + 31546483 = 31546790
397 + 31546393 = 31546790

Showing the first eight; more decompositions exist.
