Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537434, here are decompositions:

43 + 31537391 = 31537434
107 + 31537327 = 31537434
127 + 31537307 = 31537434
163 + 31537271 = 31537434
167 + 31537267 = 31537434
191 + 31537243 = 31537434
211 + 31537223 = 31537434
233 + 31537201 = 31537434

Showing the first eight; more decompositions exist.
