Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549502, here are decompositions:

3 + 31549499 = 31549502
163 + 31549339 = 31549502
421 + 31549081 = 31549502
463 + 31549039 = 31549502
541 + 31548961 = 31549502
631 + 31548871 = 31549502
739 + 31548763 = 31549502
769 + 31548733 = 31549502

Showing the first eight; more decompositions exist.
