Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619296, here are decompositions:

29 + 31619267 = 31619296
83 + 31619213 = 31619296
89 + 31619207 = 31619296
113 + 31619183 = 31619296
167 + 31619129 = 31619296
173 + 31619123 = 31619296
179 + 31619117 = 31619296
347 + 31618949 = 31619296

Showing the first eight; more decompositions exist.
