Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583424, here are decompositions:

11 + 31583413 = 31583424
71 + 31583353 = 31583424
73 + 31583351 = 31583424
101 + 31583323 = 31583424
167 + 31583257 = 31583424
277 + 31583147 = 31583424
293 + 31583131 = 31583424
337 + 31583087 = 31583424

Showing the first eight; more decompositions exist.
