Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444934, here are decompositions:

43 + 31444891 = 31444934
97 + 31444837 = 31444934
127 + 31444807 = 31444934
163 + 31444771 = 31444934
211 + 31444723 = 31444934
307 + 31444627 = 31444934
397 + 31444537 = 31444934
457 + 31444477 = 31444934

Showing the first eight; more decompositions exist.
