Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468382, here are decompositions:

13 + 31468369 = 31468382
139 + 31468243 = 31468382
151 + 31468231 = 31468382
181 + 31468201 = 31468382
223 + 31468159 = 31468382
433 + 31467949 = 31468382
571 + 31467811 = 31468382
619 + 31467763 = 31468382

Showing the first eight; more decompositions exist.
