Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583484, here are decompositions:

7 + 31583477 = 31583484
47 + 31583437 = 31583484
61 + 31583423 = 31583484
71 + 31583413 = 31583484
131 + 31583353 = 31583484
227 + 31583257 = 31583484
313 + 31583171 = 31583484
337 + 31583147 = 31583484

Showing the first eight; more decompositions exist.
