Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542772, here are decompositions:

11 + 542761 = 542772
53 + 542719 = 542772
59 + 542713 = 542772
79 + 542693 = 542772
89 + 542683 = 542772
173 + 542599 = 542772
193 + 542579 = 542772
233 + 542539 = 542772

Showing the first eight; more decompositions exist.
