Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542580, here are decompositions:

13 + 542567 = 542580
23 + 542557 = 542580
29 + 542551 = 542580
41 + 542539 = 542580
43 + 542537 = 542580
47 + 542533 = 542580
61 + 542519 = 542580
83 + 542497 = 542580

Showing the first eight; more decompositions exist.
