Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475624, here are decompositions:

13 + 31475611 = 31475624
43 + 31475581 = 31475624
181 + 31475443 = 31475624
223 + 31475401 = 31475624
283 + 31475341 = 31475624
307 + 31475317 = 31475624
337 + 31475287 = 31475624
373 + 31475251 = 31475624

Showing the first eight; more decompositions exist.
