Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540580, here are decompositions:

3 + 540577 = 540580
23 + 540557 = 540580
41 + 540539 = 540580
71 + 540509 = 540580
191 + 540389 = 540580
197 + 540383 = 540580
233 + 540347 = 540580
311 + 540269 = 540580

Showing the first eight; more decompositions exist.
