Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542182, here are decompositions:

29 + 542153 = 542182
41 + 542141 = 542182
59 + 542123 = 542182
71 + 542111 = 542182
89 + 542093 = 542182
101 + 542081 = 542182
191 + 541991 = 542182
281 + 541901 = 542182

Showing the first eight; more decompositions exist.
