Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011818, here are decompositions:

19 + 1011799 = 1011818
151 + 1011667 = 1011818
229 + 1011589 = 1011818
421 + 1011397 = 1011818
487 + 1011331 = 1011818
541 + 1011277 = 1011818
547 + 1011271 = 1011818
601 + 1011217 = 1011818

Showing the first eight; more decompositions exist.
