Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540736, here are decompositions:

23 + 540713 = 540736
47 + 540689 = 540736
59 + 540677 = 540736
107 + 540629 = 540736
137 + 540599 = 540736
149 + 540587 = 540736
179 + 540557 = 540736
197 + 540539 = 540736

Showing the first eight; more decompositions exist.
