Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542164, here are decompositions:

61 + 31542103 = 31542164
97 + 31542067 = 31542164
127 + 31542037 = 31542164
151 + 31542013 = 31542164
163 + 31542001 = 31542164
193 + 31541971 = 31542164
271 + 31541893 = 31542164
307 + 31541857 = 31542164

Showing the first eight; more decompositions exist.
