Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452094, here are decompositions:

5 + 31452089 = 31452094
53 + 31452041 = 31452094
101 + 31451993 = 31452094
257 + 31451837 = 31452094
293 + 31451801 = 31452094
383 + 31451711 = 31452094
797 + 31451297 = 31452094
983 + 31451111 = 31452094

Showing the first eight; more decompositions exist.
