Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608026, here are decompositions:

13 + 31608013 = 31608026
157 + 31607869 = 31608026
337 + 31607689 = 31608026
397 + 31607629 = 31608026
523 + 31607503 = 31608026
577 + 31607449 = 31608026
727 + 31607299 = 31608026
733 + 31607293 = 31608026

Showing the first eight; more decompositions exist.
