Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586592, here are decompositions:

13 + 31586579 = 31586592
83 + 31586509 = 31586592
109 + 31586483 = 31586592
131 + 31586461 = 31586592
241 + 31586351 = 31586592
281 + 31586311 = 31586592
311 + 31586281 = 31586592
421 + 31586171 = 31586592

Showing the first eight; more decompositions exist.
