Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475116, here are decompositions:

5 + 31475111 = 31475116
17 + 31475099 = 31475116
47 + 31475069 = 31475116
107 + 31475009 = 31475116
353 + 31474763 = 31475116
383 + 31474733 = 31475116
443 + 31474673 = 31475116
557 + 31474559 = 31475116

Showing the first eight; more decompositions exist.
