Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583426, here are decompositions:

3 + 31583423 = 31583426
13 + 31583413 = 31583426
73 + 31583353 = 31583426
103 + 31583323 = 31583426
157 + 31583269 = 31583426
379 + 31583047 = 31583426
607 + 31582819 = 31583426
937 + 31582489 = 31583426

Showing the first eight; more decompositions exist.
