Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540178, here are decompositions:

5 + 540173 = 540178
11 + 540167 = 540178
29 + 540149 = 540178
59 + 540119 = 540178
137 + 540041 = 540178
257 + 539921 = 540178
281 + 539897 = 540178
449 + 539729 = 540178

Showing the first eight; more decompositions exist.
