Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576588, here are decompositions:

5 + 31576583 = 31576588
47 + 31576541 = 31576588
59 + 31576529 = 31576588
149 + 31576439 = 31576588
179 + 31576409 = 31576588
347 + 31576241 = 31576588
389 + 31576199 = 31576588
401 + 31576187 = 31576588

Showing the first eight; more decompositions exist.
