Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522060, here are decompositions:

41 + 31522019 = 31522060
47 + 31522013 = 31522060
83 + 31521977 = 31522060
107 + 31521953 = 31522060
173 + 31521887 = 31522060
197 + 31521863 = 31522060
347 + 31521713 = 31522060
389 + 31521671 = 31522060

Showing the first eight; more decompositions exist.
