Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143420, here are decompositions:

7 + 143413 = 143420
19 + 143401 = 143420
139 + 143281 = 143420
157 + 143263 = 143420
163 + 143257 = 143420
181 + 143239 = 143420
223 + 143197 = 143420
283 + 143137 = 143420

Showing the first eight; more decompositions exist.
