Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583276, here are decompositions:

7 + 31583269 = 31583276
19 + 31583257 = 31583276
139 + 31583137 = 31583276
229 + 31583047 = 31583276
379 + 31582897 = 31583276
457 + 31582819 = 31583276
499 + 31582777 = 31583276
547 + 31582729 = 31583276

Showing the first eight; more decompositions exist.
