Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492434, here are decompositions:

5 + 31492429 = 31492434
11 + 31492423 = 31492434
13 + 31492421 = 31492434
31 + 31492403 = 31492434
41 + 31492393 = 31492434
97 + 31492337 = 31492434
157 + 31492277 = 31492434
173 + 31492261 = 31492434

Showing the first eight; more decompositions exist.
