Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540978, here are decompositions:

17 + 540961 = 540978
71 + 540907 = 540978
101 + 540877 = 540978
107 + 540871 = 540978
127 + 540851 = 540978
197 + 540781 = 540978
199 + 540779 = 540978
227 + 540751 = 540978

Showing the first eight; more decompositions exist.
