Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546754, here are decompositions:

13 + 31546741 = 31546754
37 + 31546717 = 31546754
97 + 31546657 = 31546754
157 + 31546597 = 31546754
163 + 31546591 = 31546754
181 + 31546573 = 31546754
271 + 31546483 = 31546754
367 + 31546387 = 31546754

Showing the first eight; more decompositions exist.
