Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498824, here are decompositions:

11 + 31498813 = 31498824
13 + 31498811 = 31498824
61 + 31498763 = 31498824
83 + 31498741 = 31498824
167 + 31498657 = 31498824
233 + 31498591 = 31498824
277 + 31498547 = 31498824
283 + 31498541 = 31498824

Showing the first eight; more decompositions exist.
