Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583406, here are decompositions:

53 + 31583353 = 31583406
83 + 31583323 = 31583406
137 + 31583269 = 31583406
149 + 31583257 = 31583406
269 + 31583137 = 31583406
359 + 31583047 = 31583406
373 + 31583033 = 31583406
383 + 31583023 = 31583406

Showing the first eight; more decompositions exist.
