Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583454, here are decompositions:

5 + 31583449 = 31583454
17 + 31583437 = 31583454
31 + 31583423 = 31583454
41 + 31583413 = 31583454
101 + 31583353 = 31583454
103 + 31583351 = 31583454
131 + 31583323 = 31583454
173 + 31583281 = 31583454

Showing the first eight; more decompositions exist.
