Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520952, here are decompositions:

41 + 31520911 = 31520952
53 + 31520899 = 31520952
101 + 31520851 = 31520952
191 + 31520761 = 31520952
233 + 31520719 = 31520952
251 + 31520701 = 31520952
293 + 31520659 = 31520952
373 + 31520579 = 31520952

Showing the first eight; more decompositions exist.
