Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529306, here are decompositions:

37 + 31529269 = 31529306
139 + 31529167 = 31529306
157 + 31529149 = 31529306
199 + 31529107 = 31529306
313 + 31528993 = 31529306
337 + 31528969 = 31529306
397 + 31528909 = 31529306
463 + 31528843 = 31529306

Showing the first eight; more decompositions exist.
