Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540806, here are decompositions:

3 + 540803 = 540806
37 + 540769 = 540806
103 + 540703 = 540806
109 + 540697 = 540806
127 + 540679 = 540806
193 + 540613 = 540806
229 + 540577 = 540806
337 + 540469 = 540806

Showing the first eight; more decompositions exist.
