Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549304, here are decompositions:

67 + 31549237 = 31549304
97 + 31549207 = 31549304
103 + 31549201 = 31549304
223 + 31549081 = 31549304
307 + 31548997 = 31549304
433 + 31548871 = 31549304
487 + 31548817 = 31549304
541 + 31548763 = 31549304

Showing the first eight; more decompositions exist.
