Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543050, here are decompositions:

31 + 31543019 = 31543050
41 + 31543009 = 31543050
59 + 31542991 = 31543050
79 + 31542971 = 31543050
83 + 31542967 = 31543050
101 + 31542949 = 31543050
107 + 31542943 = 31543050
109 + 31542941 = 31543050

Showing the first eight; more decompositions exist.
