Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584044, here are decompositions:

61 + 31583983 = 31584044
73 + 31583971 = 31584044
103 + 31583941 = 31584044
181 + 31583863 = 31584044
241 + 31583803 = 31584044
523 + 31583521 = 31584044
607 + 31583437 = 31584044
631 + 31583413 = 31584044

Showing the first eight; more decompositions exist.
