Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449796, here are decompositions:

5 + 31449791 = 31449796
29 + 31449767 = 31449796
107 + 31449689 = 31449796
149 + 31449647 = 31449796
167 + 31449629 = 31449796
227 + 31449569 = 31449796
239 + 31449557 = 31449796
269 + 31449527 = 31449796

Showing the first eight; more decompositions exist.
