Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540018, here are decompositions:

71 + 539947 = 540018
97 + 539921 = 540018
137 + 539881 = 540018
179 + 539839 = 540018
181 + 539837 = 540018
257 + 539761 = 540018
307 + 539711 = 540018
331 + 539687 = 540018

Showing the first eight; more decompositions exist.
