Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590852, here are decompositions:

5 + 31590847 = 31590852
11 + 31590841 = 31590852
19 + 31590833 = 31590852
61 + 31590791 = 31590852
89 + 31590763 = 31590852
113 + 31590739 = 31590852
193 + 31590659 = 31590852
263 + 31590589 = 31590852

Showing the first eight; more decompositions exist.
