Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567588, here are decompositions:

29 + 31567559 = 31567588
137 + 31567451 = 31567588
191 + 31567397 = 31567588
317 + 31567271 = 31567588
347 + 31567241 = 31567588
431 + 31567157 = 31567588
677 + 31566911 = 31567588
761 + 31566827 = 31567588

Showing the first eight; more decompositions exist.
