Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475574, here are decompositions:

83 + 31475491 = 31475574
103 + 31475471 = 31475574
131 + 31475443 = 31475574
167 + 31475407 = 31475574
173 + 31475401 = 31475574
181 + 31475393 = 31475574
233 + 31475341 = 31475574
257 + 31475317 = 31475574

Showing the first eight; more decompositions exist.
