Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580852, here are decompositions:

31 + 31580821 = 31580852
73 + 31580779 = 31580852
313 + 31580539 = 31580852
349 + 31580503 = 31580852
613 + 31580239 = 31580852
619 + 31580233 = 31580852
631 + 31580221 = 31580852
733 + 31580119 = 31580852

Showing the first eight; more decompositions exist.
