Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583412, here are decompositions:

59 + 31583353 = 31583412
61 + 31583351 = 31583412
89 + 31583323 = 31583412
131 + 31583281 = 31583412
241 + 31583171 = 31583412
281 + 31583131 = 31583412
331 + 31583081 = 31583412
379 + 31583033 = 31583412

Showing the first eight; more decompositions exist.
