Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494058, here are decompositions:

5 + 31494053 = 31494058
17 + 31494041 = 31494058
59 + 31493999 = 31494058
107 + 31493951 = 31494058
131 + 31493927 = 31494058
149 + 31493909 = 31494058
269 + 31493789 = 31494058
347 + 31493711 = 31494058

Showing the first eight; more decompositions exist.
