Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532090, here are decompositions:

19 + 31532071 = 31532090
181 + 31531909 = 31532090
277 + 31531813 = 31532090
463 + 31531627 = 31532090
607 + 31531483 = 31532090
619 + 31531471 = 31532090
673 + 31531417 = 31532090
691 + 31531399 = 31532090

Showing the first eight; more decompositions exist.
