Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549454, here are decompositions:

3 + 31549451 = 31549454
43 + 31549411 = 31549454
73 + 31549381 = 31549454
127 + 31549327 = 31549454
271 + 31549183 = 31549454
337 + 31549117 = 31549454
367 + 31549087 = 31549454
373 + 31549081 = 31549454

Showing the first eight; more decompositions exist.
