Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586524, here are decompositions:

23 + 31586501 = 31586524
41 + 31586483 = 31586524
173 + 31586351 = 31586524
251 + 31586273 = 31586524
353 + 31586171 = 31586524
383 + 31586141 = 31586524
467 + 31586057 = 31586524
521 + 31586003 = 31586524

Showing the first eight; more decompositions exist.
