Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583692, here are decompositions:

5 + 31583687 = 31583692
29 + 31583663 = 31583692
59 + 31583633 = 31583692
71 + 31583621 = 31583692
131 + 31583561 = 31583692
269 + 31583423 = 31583692
521 + 31583171 = 31583692
641 + 31583051 = 31583692

Showing the first eight; more decompositions exist.
