Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566926, here are decompositions:

7 + 31566919 = 31566926
109 + 31566817 = 31566926
163 + 31566763 = 31566926
337 + 31566589 = 31566926
367 + 31566559 = 31566926
379 + 31566547 = 31566926
409 + 31566517 = 31566926
439 + 31566487 = 31566926

Showing the first eight; more decompositions exist.
