Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449852, here are decompositions:

29 + 31449823 = 31449852
61 + 31449791 = 31449852
101 + 31449751 = 31449852
113 + 31449739 = 31449852
151 + 31449701 = 31449852
163 + 31449689 = 31449852
173 + 31449679 = 31449852
179 + 31449673 = 31449852

Showing the first eight; more decompositions exist.
