Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583546, here are decompositions:

19 + 31583527 = 31583546
37 + 31583509 = 31583546
97 + 31583449 = 31583546
109 + 31583437 = 31583546
193 + 31583353 = 31583546
223 + 31583323 = 31583546
277 + 31583269 = 31583546
409 + 31583137 = 31583546

Showing the first eight; more decompositions exist.
