Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492932, here are decompositions:

11 + 31492921 = 31492932
73 + 31492859 = 31492932
83 + 31492849 = 31492932
131 + 31492801 = 31492932
151 + 31492781 = 31492932
181 + 31492751 = 31492932
241 + 31492691 = 31492932
269 + 31492663 = 31492932

Showing the first eight; more decompositions exist.
