Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522030, here are decompositions:

11 + 31522019 = 31522030
17 + 31522013 = 31522030
53 + 31521977 = 31522030
167 + 31521863 = 31522030
179 + 31521851 = 31522030
317 + 31521713 = 31522030
347 + 31521683 = 31522030
359 + 31521671 = 31522030

Showing the first eight; more decompositions exist.
