Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472922, here are decompositions:

31 + 31472891 = 31472922
43 + 31472879 = 31472922
71 + 31472851 = 31472922
73 + 31472849 = 31472922
83 + 31472839 = 31472922
109 + 31472813 = 31472922
149 + 31472773 = 31472922
199 + 31472723 = 31472922

Showing the first eight; more decompositions exist.
