Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465754, here are decompositions:

7 + 31465747 = 31465754
13 + 31465741 = 31465754
43 + 31465711 = 31465754
193 + 31465561 = 31465754
337 + 31465417 = 31465754
433 + 31465321 = 31465754
571 + 31465183 = 31465754
577 + 31465177 = 31465754

Showing the first eight; more decompositions exist.
