Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583396, here are decompositions:

43 + 31583353 = 31583396
73 + 31583323 = 31583396
127 + 31583269 = 31583396
139 + 31583257 = 31583396
349 + 31583047 = 31583396
373 + 31583023 = 31583396
499 + 31582897 = 31583396
577 + 31582819 = 31583396

Showing the first eight; more decompositions exist.
