Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449324, here are decompositions:

37 + 31449287 = 31449324
61 + 31449263 = 31449324
83 + 31449241 = 31449324
197 + 31449127 = 31449324
241 + 31449083 = 31449324
271 + 31449053 = 31449324
281 + 31449043 = 31449324
307 + 31449017 = 31449324

Showing the first eight; more decompositions exist.
