Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492926, here are decompositions:

5 + 31492921 = 31492926
19 + 31492907 = 31492926
67 + 31492859 = 31492926
79 + 31492847 = 31492926
89 + 31492837 = 31492926
149 + 31492777 = 31492926
229 + 31492697 = 31492926
263 + 31492663 = 31492926

Showing the first eight; more decompositions exist.
