Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453092, here are decompositions:

53 + 31453039 = 31453092
71 + 31453021 = 31453092
149 + 31452943 = 31453092
191 + 31452901 = 31453092
233 + 31452859 = 31453092
241 + 31452851 = 31453092
263 + 31452829 = 31453092
353 + 31452739 = 31453092

Showing the first eight; more decompositions exist.
