Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543092, here are decompositions:

13 + 31543079 = 31543092
23 + 31543069 = 31543092
73 + 31543019 = 31543092
83 + 31543009 = 31543092
101 + 31542991 = 31543092
149 + 31542943 = 31543092
151 + 31542941 = 31543092
181 + 31542911 = 31543092

Showing the first eight; more decompositions exist.
