Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498722, here are decompositions:

19 + 31498703 = 31498722
83 + 31498639 = 31498722
131 + 31498591 = 31498722
163 + 31498559 = 31498722
173 + 31498549 = 31498722
181 + 31498541 = 31498722
193 + 31498529 = 31498722
223 + 31498499 = 31498722

Showing the first eight; more decompositions exist.
