Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542290, here are decompositions:

29 + 542261 = 542290
53 + 542237 = 542290
71 + 542219 = 542290
83 + 542207 = 542290
101 + 542189 = 542290
107 + 542183 = 542290
137 + 542153 = 542290
149 + 542141 = 542290

Showing the first eight; more decompositions exist.
