Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450592, here are decompositions:

3 + 31450589 = 31450592
13 + 31450579 = 31450592
109 + 31450483 = 31450592
163 + 31450429 = 31450592
181 + 31450411 = 31450592
223 + 31450369 = 31450592
241 + 31450351 = 31450592
373 + 31450219 = 31450592

Showing the first eight; more decompositions exist.
