Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587634, here are decompositions:

11 + 31587623 = 31587634
17 + 31587617 = 31587634
47 + 31587587 = 31587634
107 + 31587527 = 31587634
137 + 31587497 = 31587634
227 + 31587407 = 31587634
293 + 31587341 = 31587634
317 + 31587317 = 31587634

Showing the first eight; more decompositions exist.
