Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452058, here are decompositions:

17 + 31452041 = 31452058
59 + 31451999 = 31452058
89 + 31451969 = 31452058
149 + 31451909 = 31452058
251 + 31451807 = 31452058
257 + 31451801 = 31452058
347 + 31451711 = 31452058
359 + 31451699 = 31452058

Showing the first eight; more decompositions exist.
