Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558092, here are decompositions:

11 + 31558081 = 31558092
19 + 31558073 = 31558092
29 + 31558063 = 31558092
43 + 31558049 = 31558092
53 + 31558039 = 31558092
73 + 31558019 = 31558092
79 + 31558013 = 31558092
109 + 31557983 = 31558092

Showing the first eight; more decompositions exist.
