Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542014, here are decompositions:

3 + 31542011 = 31542014
13 + 31542001 = 31542014
37 + 31541977 = 31542014
43 + 31541971 = 31542014
157 + 31541857 = 31542014
277 + 31541737 = 31542014
307 + 31541707 = 31542014
337 + 31541677 = 31542014

Showing the first eight; more decompositions exist.
