Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583354, here are decompositions:

3 + 31583351 = 31583354
31 + 31583323 = 31583354
73 + 31583281 = 31583354
97 + 31583257 = 31583354
223 + 31583131 = 31583354
307 + 31583047 = 31583354
331 + 31583023 = 31583354
373 + 31582981 = 31583354

Showing the first eight; more decompositions exist.
