Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549298, here are decompositions:

61 + 31549237 = 31549298
97 + 31549201 = 31549298
181 + 31549117 = 31549298
199 + 31549099 = 31549298
211 + 31549087 = 31549298
337 + 31548961 = 31549298
541 + 31548757 = 31549298
601 + 31548697 = 31549298

Showing the first eight; more decompositions exist.
