Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490352, here are decompositions:

13 + 31490339 = 31490352
29 + 31490323 = 31490352
53 + 31490299 = 31490352
71 + 31490281 = 31490352
163 + 31490189 = 31490352
233 + 31490119 = 31490352
263 + 31490089 = 31490352
353 + 31489999 = 31490352

Showing the first eight; more decompositions exist.
