Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449234, here are decompositions:

43 + 31449191 = 31449234
71 + 31449163 = 31449234
107 + 31449127 = 31449234
151 + 31449083 = 31449234
163 + 31449071 = 31449234
181 + 31449053 = 31449234
191 + 31449043 = 31449234
197 + 31449037 = 31449234

Showing the first eight; more decompositions exist.
