Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583762, here are decompositions:

13 + 31583749 = 31583762
61 + 31583701 = 31583762
103 + 31583659 = 31583762
241 + 31583521 = 31583762
313 + 31583449 = 31583762
349 + 31583413 = 31583762
409 + 31583353 = 31583762
439 + 31583323 = 31583762

Showing the first eight; more decompositions exist.
