Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590748, here are decompositions:

11 + 31590737 = 31590748
17 + 31590731 = 31590748
89 + 31590659 = 31590748
131 + 31590617 = 31590748
191 + 31590557 = 31590748
197 + 31590551 = 31590748
269 + 31590479 = 31590748
281 + 31590467 = 31590748

Showing the first eight; more decompositions exist.
