Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492876, here are decompositions:

17 + 31492859 = 31492876
29 + 31492847 = 31492876
179 + 31492697 = 31492876
347 + 31492529 = 31492876
383 + 31492493 = 31492876
557 + 31492319 = 31492876
599 + 31492277 = 31492876
617 + 31492259 = 31492876

Showing the first eight; more decompositions exist.
