Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549342, here are decompositions:

3 + 31549339 = 31549342
5 + 31549337 = 31549342
101 + 31549241 = 31549342
359 + 31548983 = 31549342
389 + 31548953 = 31549342
593 + 31548749 = 31549342
599 + 31548743 = 31549342
683 + 31548659 = 31549342

Showing the first eight; more decompositions exist.
