Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549524, here are decompositions:

73 + 31549451 = 31549524
113 + 31549411 = 31549524
151 + 31549373 = 31549524
197 + 31549327 = 31549524
283 + 31549241 = 31549524
317 + 31549207 = 31549524
443 + 31549081 = 31549524
541 + 31548983 = 31549524

Showing the first eight; more decompositions exist.
