Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444754, here are decompositions:

31 + 31444723 = 31444754
37 + 31444717 = 31444754
73 + 31444681 = 31444754
127 + 31444627 = 31444754
163 + 31444591 = 31444754
181 + 31444573 = 31444754
277 + 31444477 = 31444754
283 + 31444471 = 31444754

Showing the first eight; more decompositions exist.
