Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498434, here are decompositions:

7 + 31498427 = 31498434
13 + 31498421 = 31498434
67 + 31498367 = 31498434
127 + 31498307 = 31498434
157 + 31498277 = 31498434
181 + 31498253 = 31498434
241 + 31498193 = 31498434
283 + 31498151 = 31498434

Showing the first eight; more decompositions exist.
