Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444964, here are decompositions:

73 + 31444891 = 31444964
127 + 31444837 = 31444964
151 + 31444813 = 31444964
157 + 31444807 = 31444964
163 + 31444801 = 31444964
193 + 31444771 = 31444964
241 + 31444723 = 31444964
283 + 31444681 = 31444964

Showing the first eight; more decompositions exist.
