Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475608, here are decompositions:

11 + 31475597 = 31475608
29 + 31475579 = 31475608
137 + 31475471 = 31475608
149 + 31475459 = 31475608
179 + 31475429 = 31475608
419 + 31475189 = 31475608
449 + 31475159 = 31475608
467 + 31475141 = 31475608

Showing the first eight; more decompositions exist.
