Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498494, here are decompositions:

23 + 31498471 = 31498494
31 + 31498463 = 31498494
67 + 31498427 = 31498494
73 + 31498421 = 31498494
127 + 31498367 = 31498494
151 + 31498343 = 31498494
241 + 31498253 = 31498494
277 + 31498217 = 31498494

Showing the first eight; more decompositions exist.
