Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546736, here are decompositions:

19 + 31546717 = 31546736
73 + 31546663 = 31546736
79 + 31546657 = 31546736
103 + 31546633 = 31546736
139 + 31546597 = 31546736
163 + 31546573 = 31546736
349 + 31546387 = 31546736
367 + 31546369 = 31546736

Showing the first eight; more decompositions exist.
