Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492534, here are decompositions:

5 + 31492529 = 31492534
41 + 31492493 = 31492534
113 + 31492421 = 31492534
131 + 31492403 = 31492534
197 + 31492337 = 31492534
257 + 31492277 = 31492534
443 + 31492091 = 31492534
461 + 31492073 = 31492534

Showing the first eight; more decompositions exist.
