Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449752, here are decompositions:

13 + 31449739 = 31449752
73 + 31449679 = 31449752
79 + 31449673 = 31449752
163 + 31449589 = 31449752
181 + 31449571 = 31449752
199 + 31449553 = 31449752
331 + 31449421 = 31449752
349 + 31449403 = 31449752

Showing the first eight; more decompositions exist.
