Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540880, here are decompositions:

3 + 540877 = 540880
17 + 540863 = 540880
29 + 540851 = 540880
71 + 540809 = 540880
101 + 540779 = 540880
107 + 540773 = 540880
167 + 540713 = 540880
191 + 540689 = 540880

Showing the first eight; more decompositions exist.
