Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583492, here are decompositions:

43 + 31583449 = 31583492
79 + 31583413 = 31583492
139 + 31583353 = 31583492
211 + 31583281 = 31583492
223 + 31583269 = 31583492
541 + 31582951 = 31583492
601 + 31582891 = 31583492
673 + 31582819 = 31583492

Showing the first eight; more decompositions exist.
