Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583852, here are decompositions:

43 + 31583809 = 31583852
73 + 31583779 = 31583852
103 + 31583749 = 31583852
151 + 31583701 = 31583852
193 + 31583659 = 31583852
211 + 31583641 = 31583852
331 + 31583521 = 31583852
439 + 31583413 = 31583852

Showing the first eight; more decompositions exist.
