Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487592, here are decompositions:

11 + 31487581 = 31487592
41 + 31487551 = 31487592
53 + 31487539 = 31487592
79 + 31487513 = 31487592
173 + 31487419 = 31487592
181 + 31487411 = 31487592
211 + 31487381 = 31487592
223 + 31487369 = 31487592

Showing the first eight; more decompositions exist.
