Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583678, here are decompositions:

19 + 31583659 = 31583678
37 + 31583641 = 31583678
151 + 31583527 = 31583678
157 + 31583521 = 31583678
229 + 31583449 = 31583678
241 + 31583437 = 31583678
397 + 31583281 = 31583678
409 + 31583269 = 31583678

Showing the first eight; more decompositions exist.
