Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494094, here are decompositions:

3 + 31494091 = 31494094
11 + 31494083 = 31494094
41 + 31494053 = 31494094
53 + 31494041 = 31494094
167 + 31493927 = 31494094
311 + 31493783 = 31494094
383 + 31493711 = 31494094
521 + 31493573 = 31494094

Showing the first eight; more decompositions exist.
