Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583592, here are decompositions:

31 + 31583561 = 31583592
43 + 31583549 = 31583592
71 + 31583521 = 31583592
83 + 31583509 = 31583592
179 + 31583413 = 31583592
239 + 31583353 = 31583592
241 + 31583351 = 31583592
269 + 31583323 = 31583592

Showing the first eight; more decompositions exist.
