Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628092, here are decompositions:

3 + 31628089 = 31628092
71 + 31628021 = 31628092
113 + 31627979 = 31628092
131 + 31627961 = 31628092
281 + 31627811 = 31628092
443 + 31627649 = 31628092
491 + 31627601 = 31628092
701 + 31627391 = 31628092

Showing the first eight; more decompositions exist.
