Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474700, here are decompositions:

7 + 31474693 = 31474700
13 + 31474687 = 31474700
31 + 31474669 = 31474700
151 + 31474549 = 31474700
181 + 31474519 = 31474700
199 + 31474501 = 31474700
211 + 31474489 = 31474700
277 + 31474423 = 31474700

Showing the first eight; more decompositions exist.
