Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540802, here are decompositions:

23 + 540779 = 540802
29 + 540773 = 540802
89 + 540713 = 540802
113 + 540689 = 540802
173 + 540629 = 540802
191 + 540611 = 540802
263 + 540539 = 540802
293 + 540509 = 540802

Showing the first eight; more decompositions exist.
