Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449088, here are decompositions:

5 + 31449083 = 31449088
17 + 31449071 = 31449088
59 + 31449029 = 31449088
71 + 31449017 = 31449088
101 + 31448987 = 31449088
179 + 31448909 = 31449088
191 + 31448897 = 31449088
197 + 31448891 = 31449088

Showing the first eight; more decompositions exist.
