Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 141138, here are decompositions:

7 + 141131 = 141138
17 + 141121 = 141138
31 + 141107 = 141138
37 + 141101 = 141138
59 + 141079 = 141138
71 + 141067 = 141138
97 + 141041 = 141138
149 + 140989 = 141138

Showing the first eight; more decompositions exist.
