Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583476, here are decompositions:

53 + 31583423 = 31583476
317 + 31583159 = 31583476
389 + 31583087 = 31583476
443 + 31583033 = 31583476
563 + 31582913 = 31583476
569 + 31582907 = 31583476
653 + 31582823 = 31583476
719 + 31582757 = 31583476

Showing the first eight; more decompositions exist.
