Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468588, here are decompositions:

17 + 31468571 = 31468588
29 + 31468559 = 31468588
59 + 31468529 = 31468588
71 + 31468517 = 31468588
89 + 31468499 = 31468588
191 + 31468397 = 31468588
197 + 31468391 = 31468588
251 + 31468337 = 31468588

Showing the first eight; more decompositions exist.
