Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31092, here are decompositions:

11 + 31081 = 31092
13 + 31079 = 31092
23 + 31069 = 31092
29 + 31063 = 31092
41 + 31051 = 31092
53 + 31039 = 31092
59 + 31033 = 31092
73 + 31019 = 31092

Showing the first eight; more decompositions exist.
