Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608926, here are decompositions:

43 + 31608883 = 31608926
73 + 31608853 = 31608926
103 + 31608823 = 31608926
109 + 31608817 = 31608926
199 + 31608727 = 31608926
229 + 31608697 = 31608926
337 + 31608589 = 31608926
397 + 31608529 = 31608926

Showing the first eight; more decompositions exist.
