Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476046, here are decompositions:

29 + 31476017 = 31476046
83 + 31475963 = 31476046
137 + 31475909 = 31476046
197 + 31475849 = 31476046
233 + 31475813 = 31476046
269 + 31475777 = 31476046
449 + 31475597 = 31476046
467 + 31475579 = 31476046

Showing the first eight; more decompositions exist.
