Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493734, here are decompositions:

17 + 31493717 = 31493734
23 + 31493711 = 31493734
257 + 31493477 = 31493734
443 + 31493291 = 31493734
563 + 31493171 = 31493734
677 + 31493057 = 31493734
743 + 31492991 = 31493734
827 + 31492907 = 31493734

Showing the first eight; more decompositions exist.
