Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444814, here are decompositions:

7 + 31444807 = 31444814
13 + 31444801 = 31444814
43 + 31444771 = 31444814
97 + 31444717 = 31444814
223 + 31444591 = 31444814
241 + 31444573 = 31444814
277 + 31444537 = 31444814
337 + 31444477 = 31444814

Showing the first eight; more decompositions exist.
