Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543138, here are decompositions:

7 + 543131 = 543138
41 + 543097 = 543138
109 + 543029 = 543138
139 + 542999 = 543138
151 + 542987 = 543138
157 + 542981 = 543138
191 + 542947 = 543138
199 + 542939 = 543138

Showing the first eight; more decompositions exist.
