Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542934, here are decompositions:

23 + 31542911 = 31542934
53 + 31542881 = 31542934
107 + 31542827 = 31542934
167 + 31542767 = 31542934
257 + 31542677 = 31542934
347 + 31542587 = 31542934
557 + 31542377 = 31542934
593 + 31542341 = 31542934

Showing the first eight; more decompositions exist.
