Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583594, here are decompositions:

67 + 31583527 = 31583594
73 + 31583521 = 31583594
157 + 31583437 = 31583594
181 + 31583413 = 31583594
241 + 31583353 = 31583594
271 + 31583323 = 31583594
313 + 31583281 = 31583594
337 + 31583257 = 31583594

Showing the first eight; more decompositions exist.
