Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549604, here are decompositions:

7 + 31549597 = 31549604
13 + 31549591 = 31549604
43 + 31549561 = 31549604
193 + 31549411 = 31549604
223 + 31549381 = 31549604
277 + 31549327 = 31549604
367 + 31549237 = 31549604
397 + 31549207 = 31549604

Showing the first eight; more decompositions exist.
