Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540786, here are decompositions:

5 + 540781 = 540786
7 + 540779 = 540786
13 + 540773 = 540786
17 + 540769 = 540786
73 + 540713 = 540786
83 + 540703 = 540786
89 + 540697 = 540786
97 + 540689 = 540786

Showing the first eight; more decompositions exist.
