Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540900, here are decompositions:

23 + 540877 = 540900
29 + 540871 = 540900
37 + 540863 = 540900
97 + 540803 = 540900
127 + 540773 = 540900
131 + 540769 = 540900
149 + 540751 = 540900
197 + 540703 = 540900

Showing the first eight; more decompositions exist.
