Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583434, here are decompositions:

11 + 31583423 = 31583434
83 + 31583351 = 31583434
263 + 31583171 = 31583434
347 + 31583087 = 31583434
353 + 31583081 = 31583434
383 + 31583051 = 31583434
401 + 31583033 = 31583434
503 + 31582931 = 31583434

Showing the first eight; more decompositions exist.
