Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540814, here are decompositions:

5 + 540809 = 540814
11 + 540803 = 540814
41 + 540773 = 540814
101 + 540713 = 540814
137 + 540677 = 540814
227 + 540587 = 540814
257 + 540557 = 540814
353 + 540461 = 540814

Showing the first eight; more decompositions exist.
