Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540810, here are decompositions:

7 + 540803 = 540810
29 + 540781 = 540810
31 + 540779 = 540810
37 + 540773 = 540810
41 + 540769 = 540810
59 + 540751 = 540810
97 + 540713 = 540810
107 + 540703 = 540810

Showing the first eight; more decompositions exist.
