Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449354, here are decompositions:

31 + 31449323 = 31449354
67 + 31449287 = 31449354
107 + 31449247 = 31449354
113 + 31449241 = 31449354
163 + 31449191 = 31449354
191 + 31449163 = 31449354
227 + 31449127 = 31449354
271 + 31449083 = 31449354

Showing the first eight; more decompositions exist.
