Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475366, here are decompositions:

79 + 31475287 = 31475366
157 + 31475209 = 31475366
277 + 31475089 = 31475366
283 + 31475083 = 31475366
313 + 31475053 = 31475366
337 + 31475029 = 31475366
367 + 31474999 = 31475366
397 + 31474969 = 31475366

Showing the first eight; more decompositions exist.
