Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506932, here are decompositions:

3 + 31506929 = 31506932
103 + 31506829 = 31506932
109 + 31506823 = 31506932
139 + 31506793 = 31506932
151 + 31506781 = 31506932
409 + 31506523 = 31506932
421 + 31506511 = 31506932
601 + 31506331 = 31506932

Showing the first eight; more decompositions exist.
