Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540808, here are decompositions:

5 + 540803 = 540808
29 + 540779 = 540808
131 + 540677 = 540808
179 + 540629 = 540808
197 + 540611 = 540808
251 + 540557 = 540808
269 + 540539 = 540808
347 + 540461 = 540808

Showing the first eight; more decompositions exist.
