Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529348, here are decompositions:

79 + 31529269 = 31529348
181 + 31529167 = 31529348
199 + 31529149 = 31529348
241 + 31529107 = 31529348
379 + 31528969 = 31529348
439 + 31528909 = 31529348
541 + 31528807 = 31529348
547 + 31528801 = 31529348

Showing the first eight; more decompositions exist.
