Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540730, here are decompositions:

17 + 540713 = 540730
41 + 540689 = 540730
53 + 540677 = 540730
101 + 540629 = 540730
131 + 540599 = 540730
173 + 540557 = 540730
191 + 540539 = 540730
269 + 540461 = 540730

Showing the first eight; more decompositions exist.
