Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542108, here are decompositions:

37 + 542071 = 542108
109 + 541999 = 542108
157 + 541951 = 542108
181 + 541927 = 542108
271 + 541837 = 542108
277 + 541831 = 542108
331 + 541777 = 542108
337 + 541771 = 542108

Showing the first eight; more decompositions exist.
