Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493092, here are decompositions:

23 + 31493069 = 31493092
53 + 31493039 = 31493092
83 + 31493009 = 31493092
101 + 31492991 = 31493092
149 + 31492943 = 31493092
233 + 31492859 = 31493092
251 + 31492841 = 31493092
311 + 31492781 = 31493092

Showing the first eight; more decompositions exist.
