Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951840, here are decompositions:

11 + 951829 = 951840
37 + 951803 = 951840
53 + 951787 = 951840
59 + 951781 = 951840
151 + 951689 = 951840
181 + 951659 = 951840
191 + 951649 = 951840
193 + 951647 = 951840

Showing the first eight; more decompositions exist.
