Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606676, here are decompositions:

19 + 31606657 = 31606676
97 + 31606579 = 31606676
139 + 31606537 = 31606676
307 + 31606369 = 31606676
337 + 31606339 = 31606676
379 + 31606297 = 31606676
397 + 31606279 = 31606676
853 + 31605823 = 31606676

Showing the first eight; more decompositions exist.
