Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542006, here are decompositions:

5 + 31542001 = 31542006
17 + 31541989 = 31542006
29 + 31541977 = 31542006
73 + 31541933 = 31542006
103 + 31541903 = 31542006
107 + 31541899 = 31542006
113 + 31541893 = 31542006
137 + 31541869 = 31542006

Showing the first eight; more decompositions exist.
