Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540332, here are decompositions:

23 + 31540309 = 31540332
71 + 31540261 = 31540332
151 + 31540181 = 31540332
223 + 31540109 = 31540332
233 + 31540099 = 31540332
269 + 31540063 = 31540332
401 + 31539931 = 31540332
431 + 31539901 = 31540332

Showing the first eight; more decompositions exist.
