Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542194, here are decompositions:

5 + 542189 = 542194
11 + 542183 = 542194
41 + 542153 = 542194
53 + 542141 = 542194
71 + 542123 = 542194
83 + 542111 = 542194
101 + 542093 = 542194
113 + 542081 = 542194

Showing the first eight; more decompositions exist.
