Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475534, here are decompositions:

43 + 31475491 = 31475534
127 + 31475407 = 31475534
163 + 31475371 = 31475534
193 + 31475341 = 31475534
283 + 31475251 = 31475534
463 + 31475071 = 31475534
661 + 31474873 = 31475534
733 + 31474801 = 31475534

Showing the first eight; more decompositions exist.
