Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498932, here are decompositions:

19 + 31498913 = 31498932
53 + 31498879 = 31498932
79 + 31498853 = 31498932
83 + 31498849 = 31498932
103 + 31498829 = 31498932
191 + 31498741 = 31498932
229 + 31498703 = 31498932
293 + 31498639 = 31498932

Showing the first eight; more decompositions exist.
