Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587594, here are decompositions:

7 + 31587587 = 31587594
67 + 31587527 = 31587594
97 + 31587497 = 31587594
167 + 31587427 = 31587594
173 + 31587421 = 31587594
197 + 31587397 = 31587594
277 + 31587317 = 31587594
307 + 31587287 = 31587594

Showing the first eight; more decompositions exist.
