Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498264, here are decompositions:

11 + 31498253 = 31498264
47 + 31498217 = 31498264
71 + 31498193 = 31498264
113 + 31498151 = 31498264
257 + 31498007 = 31498264
401 + 31497863 = 31498264
461 + 31497803 = 31498264
467 + 31497797 = 31498264

Showing the first eight; more decompositions exist.
