Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542720, here are decompositions:

7 + 542713 = 542720
37 + 542683 = 542720
163 + 542557 = 542720
181 + 542539 = 542720
223 + 542497 = 542720
349 + 542371 = 542720
397 + 542323 = 542720
421 + 542299 = 542720

Showing the first eight; more decompositions exist.
