Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532036, here are decompositions:

127 + 31531909 = 31532036
223 + 31531813 = 31532036
397 + 31531639 = 31532036
409 + 31531627 = 31532036
457 + 31531579 = 31532036
619 + 31531417 = 31532036
733 + 31531303 = 31532036
769 + 31531267 = 31532036

Showing the first eight; more decompositions exist.
