Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475462, here are decompositions:

3 + 31475459 = 31475462
19 + 31475443 = 31475462
61 + 31475401 = 31475462
211 + 31475251 = 31475462
331 + 31475131 = 31475462
373 + 31475089 = 31475462
379 + 31475083 = 31475462
409 + 31475053 = 31475462

Showing the first eight; more decompositions exist.
