Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500932, here are decompositions:

13 + 31500919 = 31500932
61 + 31500871 = 31500932
79 + 31500853 = 31500932
139 + 31500793 = 31500932
241 + 31500691 = 31500932
283 + 31500649 = 31500932
373 + 31500559 = 31500932
571 + 31500361 = 31500932

Showing the first eight; more decompositions exist.
