Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540738, here are decompositions:

41 + 540697 = 540738
47 + 540691 = 540738
59 + 540679 = 540738
61 + 540677 = 540738
109 + 540629 = 540738
127 + 540611 = 540738
139 + 540599 = 540738
151 + 540587 = 540738

Showing the first eight; more decompositions exist.
