Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498876, here are decompositions:

23 + 31498853 = 31498876
29 + 31498847 = 31498876
47 + 31498829 = 31498876
113 + 31498763 = 31498876
173 + 31498703 = 31498876
317 + 31498559 = 31498876
347 + 31498529 = 31498876
359 + 31498517 = 31498876

Showing the first eight; more decompositions exist.
