Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498298, here are decompositions:

19 + 31498279 = 31498298
109 + 31498189 = 31498298
211 + 31498087 = 31498298
229 + 31498069 = 31498298
367 + 31497931 = 31498298
439 + 31497859 = 31498298
541 + 31497757 = 31498298
547 + 31497751 = 31498298

Showing the first eight; more decompositions exist.
