Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522050, here are decompositions:

29 + 31522021 = 31522050
31 + 31522019 = 31522050
37 + 31522013 = 31522050
59 + 31521991 = 31522050
71 + 31521979 = 31522050
73 + 31521977 = 31522050
97 + 31521953 = 31522050
163 + 31521887 = 31522050

Showing the first eight; more decompositions exist.
