Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485554, here are decompositions:

13 + 31485541 = 31485554
127 + 31485427 = 31485554
157 + 31485397 = 31485554
241 + 31485313 = 31485554
271 + 31485283 = 31485554
277 + 31485277 = 31485554
307 + 31485247 = 31485554
433 + 31485121 = 31485554

Showing the first eight; more decompositions exist.
