Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585694, here are decompositions:

3 + 31585691 = 31585694
31 + 31585663 = 31585694
97 + 31585597 = 31585694
157 + 31585537 = 31585694
193 + 31585501 = 31585694
241 + 31585453 = 31585694
367 + 31585327 = 31585694
433 + 31585261 = 31585694

Showing the first eight; more decompositions exist.
