Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489594, here are decompositions:

23 + 31489571 = 31489594
53 + 31489541 = 31489594
131 + 31489463 = 31489594
167 + 31489427 = 31489594
347 + 31489247 = 31489594
401 + 31489193 = 31489594
503 + 31489091 = 31489594
557 + 31489037 = 31489594

Showing the first eight; more decompositions exist.
