Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626376, here are decompositions:

17 + 31626359 = 31626376
53 + 31626323 = 31626376
167 + 31626209 = 31626376
179 + 31626197 = 31626376
389 + 31625987 = 31626376
557 + 31625819 = 31626376
569 + 31625807 = 31626376
599 + 31625777 = 31626376

Showing the first eight; more decompositions exist.
