Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583340, here are decompositions:

17 + 31583323 = 31583340
59 + 31583281 = 31583340
71 + 31583269 = 31583340
83 + 31583257 = 31583340
181 + 31583159 = 31583340
193 + 31583147 = 31583340
293 + 31583047 = 31583340
307 + 31583033 = 31583340

Showing the first eight; more decompositions exist.
