Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540778, here are decompositions:

5 + 540773 = 540778
89 + 540689 = 540778
101 + 540677 = 540778
149 + 540629 = 540778
167 + 540611 = 540778
179 + 540599 = 540778
191 + 540587 = 540778
239 + 540539 = 540778

Showing the first eight; more decompositions exist.
