Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540628, here are decompositions:

17 + 540611 = 540628
29 + 540599 = 540628
41 + 540587 = 540628
71 + 540557 = 540628
89 + 540539 = 540628
167 + 540461 = 540628
191 + 540437 = 540628
239 + 540389 = 540628

Showing the first eight; more decompositions exist.
