Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498834, here are decompositions:

5 + 31498829 = 31498834
23 + 31498811 = 31498834
71 + 31498763 = 31498834
131 + 31498703 = 31498834
293 + 31498541 = 31498834
317 + 31498517 = 31498834
467 + 31498367 = 31498834
491 + 31498343 = 31498834

Showing the first eight; more decompositions exist.
