Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472058, here are decompositions:

5 + 31472053 = 31472058
17 + 31472041 = 31472058
29 + 31472029 = 31472058
47 + 31472011 = 31472058
67 + 31471991 = 31472058
151 + 31471907 = 31472058
157 + 31471901 = 31472058
227 + 31471831 = 31472058

Showing the first eight; more decompositions exist.
