Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474554, here are decompositions:

5 + 31474549 = 31474554
53 + 31474501 = 31474554
73 + 31474481 = 31474554
131 + 31474423 = 31474554
151 + 31474403 = 31474554
157 + 31474397 = 31474554
191 + 31474363 = 31474554
197 + 31474357 = 31474554

Showing the first eight; more decompositions exist.
