Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540202, here are decompositions:

23 + 540179 = 540202
29 + 540173 = 540202
53 + 540149 = 540202
83 + 540119 = 540202
101 + 540101 = 540202
281 + 539921 = 540202
353 + 539849 = 540202
359 + 539843 = 540202

Showing the first eight; more decompositions exist.
