Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499352, here are decompositions:

11 + 31499341 = 31499352
23 + 31499329 = 31499352
29 + 31499323 = 31499352
41 + 31499311 = 31499352
43 + 31499309 = 31499352
61 + 31499291 = 31499352
113 + 31499239 = 31499352
163 + 31499189 = 31499352

Showing the first eight; more decompositions exist.
