Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540658, here are decompositions:

29 + 540629 = 540658
47 + 540611 = 540658
59 + 540599 = 540658
71 + 540587 = 540658
101 + 540557 = 540658
149 + 540509 = 540658
197 + 540461 = 540658
269 + 540389 = 540658

Showing the first eight; more decompositions exist.
