Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475122, here are decompositions:

11 + 31475111 = 31475122
23 + 31475099 = 31475122
53 + 31475069 = 31475122
113 + 31475009 = 31475122
191 + 31474931 = 31475122
293 + 31474829 = 31475122
359 + 31474763 = 31475122
389 + 31474733 = 31475122

Showing the first eight; more decompositions exist.
