Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444852, here are decompositions:

191 + 31444661 = 31444852
293 + 31444559 = 31444852
311 + 31444541 = 31444852
449 + 31444403 = 31444852
773 + 31444079 = 31444852
911 + 31443941 = 31444852
941 + 31443911 = 31444852
953 + 31443899 = 31444852

Showing the first eight; more decompositions exist.
