Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542258, here are decompositions:

7 + 542251 = 542258
61 + 542197 = 542258
109 + 542149 = 542258
127 + 542131 = 542258
139 + 542119 = 542258
271 + 541987 = 542258
307 + 541951 = 542258
331 + 541927 = 542258

Showing the first eight; more decompositions exist.
