Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498882, here are decompositions:

3 + 31498879 = 31498882
29 + 31498853 = 31498882
53 + 31498829 = 31498882
71 + 31498811 = 31498882
179 + 31498703 = 31498882
353 + 31498529 = 31498882
383 + 31498499 = 31498882
419 + 31498463 = 31498882

Showing the first eight; more decompositions exist.
