Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583432, here are decompositions:

19 + 31583413 = 31583432
79 + 31583353 = 31583432
109 + 31583323 = 31583432
151 + 31583281 = 31583432
163 + 31583269 = 31583432
409 + 31583023 = 31583432
541 + 31582891 = 31583432
613 + 31582819 = 31583432

Showing the first eight; more decompositions exist.
