Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619344, here are decompositions:

17 + 31619327 = 31619344
83 + 31619261 = 31619344
131 + 31619213 = 31619344
137 + 31619207 = 31619344
167 + 31619177 = 31619344
173 + 31619171 = 31619344
227 + 31619117 = 31619344
353 + 31618991 = 31619344

Showing the first eight; more decompositions exist.
