Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540894, here are decompositions:

17 + 540877 = 540894
23 + 540871 = 540894
31 + 540863 = 540894
43 + 540851 = 540894
71 + 540823 = 540894
113 + 540781 = 540894
181 + 540713 = 540894
191 + 540703 = 540894

Showing the first eight; more decompositions exist.
