Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531092, here are decompositions:

13 + 31531079 = 31531092
23 + 31531069 = 31531092
29 + 31531063 = 31531092
113 + 31530979 = 31531092
149 + 31530943 = 31531092
191 + 31530901 = 31531092
199 + 31530893 = 31531092
251 + 31530841 = 31531092

Showing the first eight; more decompositions exist.
