Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449058, here are decompositions:

5 + 31449053 = 31449058
29 + 31449029 = 31449058
41 + 31449017 = 31449058
71 + 31448987 = 31449058
149 + 31448909 = 31449058
167 + 31448891 = 31449058
317 + 31448741 = 31449058
359 + 31448699 = 31449058

Showing the first eight; more decompositions exist.
