Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474506, here are decompositions:

5 + 31474501 = 31474506
17 + 31474489 = 31474506
73 + 31474433 = 31474506
83 + 31474423 = 31474506
103 + 31474403 = 31474506
109 + 31474397 = 31474506
149 + 31474357 = 31474506
163 + 31474343 = 31474506

Showing the first eight; more decompositions exist.
