Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475330, here are decompositions:

13 + 31475317 = 31475330
43 + 31475287 = 31475330
79 + 31475251 = 31475330
199 + 31475131 = 31475330
223 + 31475107 = 31475330
241 + 31475089 = 31475330
277 + 31475053 = 31475330
331 + 31474999 = 31475330

Showing the first eight; more decompositions exist.
