Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951818, here are decompositions:

31 + 951787 = 951818
37 + 951781 = 951818
181 + 951637 = 951818
229 + 951589 = 951818
349 + 951469 = 951818
457 + 951361 = 951818
487 + 951331 = 951818
541 + 951277 = 951818

Showing the first eight; more decompositions exist.
