Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506092, here are decompositions:

31 + 31506061 = 31506092
61 + 31506031 = 31506092
103 + 31505989 = 31506092
109 + 31505983 = 31506092
271 + 31505821 = 31506092
283 + 31505809 = 31506092
433 + 31505659 = 31506092
523 + 31505569 = 31506092

Showing the first eight; more decompositions exist.
