Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583834, here are decompositions:

3 + 31583831 = 31583834
31 + 31583803 = 31583834
193 + 31583641 = 31583834
307 + 31583527 = 31583834
313 + 31583521 = 31583834
397 + 31583437 = 31583834
421 + 31583413 = 31583834
577 + 31583257 = 31583834

Showing the first eight; more decompositions exist.
