Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449498, here are decompositions:

5 + 31449493 = 31449498
19 + 31449479 = 31449498
89 + 31449409 = 31449498
97 + 31449401 = 31449498
137 + 31449361 = 31449498
139 + 31449359 = 31449498
211 + 31449287 = 31449498
239 + 31449259 = 31449498

Showing the first eight; more decompositions exist.
