Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537582, here are decompositions:

23 + 31537559 = 31537582
101 + 31537481 = 31537582
113 + 31537469 = 31537582
149 + 31537433 = 31537582
173 + 31537409 = 31537582
191 + 31537391 = 31537582
269 + 31537313 = 31537582
311 + 31537271 = 31537582

Showing the first eight; more decompositions exist.
