Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522892, here are decompositions:

3 + 31522889 = 31522892
19 + 31522873 = 31522892
199 + 31522693 = 31522892
223 + 31522669 = 31522892
229 + 31522663 = 31522892
433 + 31522459 = 31522892
673 + 31522219 = 31522892
1009 + 31521883 = 31522892

Showing the first eight; more decompositions exist.
