Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583954, here are decompositions:

13 + 31583941 = 31583954
43 + 31583911 = 31583954
97 + 31583857 = 31583954
151 + 31583803 = 31583954
313 + 31583641 = 31583954
433 + 31583521 = 31583954
541 + 31583413 = 31583954
601 + 31583353 = 31583954

Showing the first eight; more decompositions exist.
