Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619362, here are decompositions:

3 + 31619359 = 31619362
101 + 31619261 = 31619362
149 + 31619213 = 31619362
179 + 31619183 = 31619362
191 + 31619171 = 31619362
233 + 31619129 = 31619362
239 + 31619123 = 31619362
353 + 31619009 = 31619362

Showing the first eight; more decompositions exist.
