Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523092, here are decompositions:

11 + 31523081 = 31523092
71 + 31523021 = 31523092
89 + 31523003 = 31523092
113 + 31522979 = 31523092
131 + 31522961 = 31523092
191 + 31522901 = 31523092
269 + 31522823 = 31523092
479 + 31522613 = 31523092

Showing the first eight; more decompositions exist.
