Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540812, here are decompositions:

3 + 540809 = 540812
31 + 540781 = 540812
43 + 540769 = 540812
61 + 540751 = 540812
109 + 540703 = 540812
193 + 540619 = 540812
199 + 540613 = 540812
271 + 540541 = 540812

Showing the first eight; more decompositions exist.
