Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471050, here are decompositions:

7 + 31471043 = 31471050
19 + 31471031 = 31471050
43 + 31471007 = 31471050
53 + 31470997 = 31471050
59 + 31470991 = 31471050
73 + 31470977 = 31471050
97 + 31470953 = 31471050
109 + 31470941 = 31471050

Showing the first eight; more decompositions exist.
