Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537932, here are decompositions:

11 + 31537921 = 31537932
29 + 31537903 = 31537932
43 + 31537889 = 31537932
61 + 31537871 = 31537932
71 + 31537861 = 31537932
73 + 31537859 = 31537932
89 + 31537843 = 31537932
109 + 31537823 = 31537932

Showing the first eight; more decompositions exist.
