Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606058, here are decompositions:

7 + 31606051 = 31606058
181 + 31605877 = 31606058
277 + 31605781 = 31606058
331 + 31605727 = 31606058
439 + 31605619 = 31606058
487 + 31605571 = 31606058
541 + 31605517 = 31606058
619 + 31605439 = 31606058

Showing the first eight; more decompositions exist.
