Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606498, here are decompositions:

5 + 31606493 = 31606498
29 + 31606469 = 31606498
101 + 31606397 = 31606498
167 + 31606331 = 31606498
179 + 31606319 = 31606498
311 + 31606187 = 31606498
317 + 31606181 = 31606498
401 + 31606097 = 31606498

Showing the first eight; more decompositions exist.
