Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540884, here are decompositions:

7 + 540877 = 540884
13 + 540871 = 540884
61 + 540823 = 540884
103 + 540781 = 540884
181 + 540703 = 540884
193 + 540691 = 540884
271 + 540613 = 540884
307 + 540577 = 540884

Showing the first eight; more decompositions exist.
