Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546730, here are decompositions:

13 + 31546717 = 31546730
67 + 31546663 = 31546730
73 + 31546657 = 31546730
97 + 31546633 = 31546730
109 + 31546621 = 31546730
139 + 31546591 = 31546730
157 + 31546573 = 31546730
337 + 31546393 = 31546730

Showing the first eight; more decompositions exist.
