Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540992, here are decompositions:

3 + 540989 = 540992
31 + 540961 = 540992
211 + 540781 = 540992
223 + 540769 = 540992
241 + 540751 = 540992
313 + 540679 = 540992
373 + 540619 = 540992
379 + 540613 = 540992

Showing the first eight; more decompositions exist.
