Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449246, here are decompositions:

5 + 31449241 = 31449246
13 + 31449233 = 31449246
67 + 31449179 = 31449246
83 + 31449163 = 31449246
163 + 31449083 = 31449246
193 + 31449053 = 31449246
229 + 31449017 = 31449246
337 + 31448909 = 31449246

Showing the first eight; more decompositions exist.
