Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476330, here are decompositions:

13 + 31476317 = 31476330
47 + 31476283 = 31476330
79 + 31476251 = 31476330
173 + 31476157 = 31476330
181 + 31476149 = 31476330
211 + 31476119 = 31476330
233 + 31476097 = 31476330
257 + 31476073 = 31476330

Showing the first eight; more decompositions exist.
