Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606958, here are decompositions:

7 + 31606951 = 31606958
79 + 31606879 = 31606958
277 + 31606681 = 31606958
307 + 31606651 = 31606958
379 + 31606579 = 31606958
421 + 31606537 = 31606958
547 + 31606411 = 31606958
571 + 31606387 = 31606958

Showing the first eight; more decompositions exist.
