Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532258, here are decompositions:

31 + 31532227 = 31532258
337 + 31531921 = 31532258
349 + 31531909 = 31532258
619 + 31531639 = 31532258
631 + 31531627 = 31532258
787 + 31531471 = 31532258
859 + 31531399 = 31532258
991 + 31531267 = 31532258

Showing the first eight; more decompositions exist.
