Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583672, here are decompositions:

13 + 31583659 = 31583672
31 + 31583641 = 31583672
151 + 31583521 = 31583672
163 + 31583509 = 31583672
223 + 31583449 = 31583672
349 + 31583323 = 31583672
541 + 31583131 = 31583672
691 + 31582981 = 31583672

Showing the first eight; more decompositions exist.
