Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475554, here are decompositions:

83 + 31475471 = 31475554
101 + 31475453 = 31475554
167 + 31475387 = 31475554
233 + 31475321 = 31475554
311 + 31475243 = 31475554
443 + 31475111 = 31475554
557 + 31474997 = 31475554
821 + 31474733 = 31475554

Showing the first eight; more decompositions exist.
