Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583326, here are decompositions:

3 + 31583323 = 31583326
167 + 31583159 = 31583326
179 + 31583147 = 31583326
239 + 31583087 = 31583326
293 + 31583033 = 31583326
389 + 31582937 = 31583326
419 + 31582907 = 31583326
479 + 31582847 = 31583326

Showing the first eight; more decompositions exist.
