Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528092, here are decompositions:

23 + 31528069 = 31528092
73 + 31528019 = 31528092
151 + 31527941 = 31528092
179 + 31527913 = 31528092
263 + 31527829 = 31528092
311 + 31527781 = 31528092
383 + 31527709 = 31528092
389 + 31527703 = 31528092

Showing the first eight; more decompositions exist.
