Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605926, here are decompositions:

13 + 31605913 = 31605926
103 + 31605823 = 31605926
199 + 31605727 = 31605926
229 + 31605697 = 31605926
307 + 31605619 = 31605926
349 + 31605577 = 31605926
409 + 31605517 = 31605926
487 + 31605439 = 31605926

Showing the first eight; more decompositions exist.
