Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493116, here are decompositions:

47 + 31493069 = 31493116
59 + 31493057 = 31493116
107 + 31493009 = 31493116
173 + 31492943 = 31493116
257 + 31492859 = 31493116
269 + 31492847 = 31493116
359 + 31492757 = 31493116
419 + 31492697 = 31493116

Showing the first eight; more decompositions exist.
