Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542152, here are decompositions:

3 + 31542149 = 31542152
139 + 31542013 = 31542152
151 + 31542001 = 31542152
163 + 31541989 = 31542152
181 + 31541971 = 31542152
283 + 31541869 = 31542152
541 + 31541611 = 31542152
571 + 31541581 = 31542152

Showing the first eight; more decompositions exist.
