Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542228, here are decompositions:

31 + 542197 = 542228
61 + 542167 = 542228
79 + 542149 = 542228
97 + 542131 = 542228
109 + 542119 = 542228
157 + 542071 = 542228
229 + 541999 = 542228
241 + 541987 = 542228

Showing the first eight; more decompositions exist.
