Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449954, here are decompositions:

17 + 31449937 = 31449954
23 + 31449931 = 31449954
31 + 31449923 = 31449954
83 + 31449871 = 31449954
101 + 31449853 = 31449954
131 + 31449823 = 31449954
163 + 31449791 = 31449954
197 + 31449757 = 31449954

Showing the first eight; more decompositions exist.
