Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546502, here are decompositions:

19 + 31546483 = 31546502
109 + 31546393 = 31546502
151 + 31546351 = 31546502
199 + 31546303 = 31546502
223 + 31546279 = 31546502
271 + 31546231 = 31546502
349 + 31546153 = 31546502
373 + 31546129 = 31546502

Showing the first eight; more decompositions exist.
