Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133818, here are decompositions:

5 + 133813 = 133818
7 + 133811 = 133818
17 + 133801 = 133818
37 + 133781 = 133818
101 + 133717 = 133818
107 + 133711 = 133818
109 + 133709 = 133818
127 + 133691 = 133818

Showing the first eight; more decompositions exist.
