Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542066, here are decompositions:

3 + 542063 = 542066
13 + 542053 = 542066
43 + 542023 = 542066
67 + 541999 = 542066
73 + 541993 = 542066
79 + 541987 = 542066
139 + 541927 = 542066
229 + 541837 = 542066

Showing the first eight; more decompositions exist.
