Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475506, here are decompositions:

17 + 31475489 = 31475506
47 + 31475459 = 31475506
53 + 31475453 = 31475506
113 + 31475393 = 31475506
263 + 31475243 = 31475506
317 + 31475189 = 31475506
347 + 31475159 = 31475506
509 + 31474997 = 31475506

Showing the first eight; more decompositions exist.
