Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542050, here are decompositions:

13 + 31542037 = 31542050
19 + 31542031 = 31542050
37 + 31542013 = 31542050
61 + 31541989 = 31542050
73 + 31541977 = 31542050
79 + 31541971 = 31542050
151 + 31541899 = 31542050
157 + 31541893 = 31542050

Showing the first eight; more decompositions exist.
