Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583652, here are decompositions:

11 + 31583641 = 31583652
19 + 31583633 = 31583652
31 + 31583621 = 31583652
103 + 31583549 = 31583652
131 + 31583521 = 31583652
229 + 31583423 = 31583652
239 + 31583413 = 31583652
383 + 31583269 = 31583652

Showing the first eight; more decompositions exist.
