Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144138, here are decompositions:

67 + 144071 = 144138
101 + 144037 = 144138
107 + 144031 = 144138
139 + 143999 = 144138
157 + 143981 = 144138
167 + 143971 = 144138
191 + 143947 = 144138
229 + 143909 = 144138

Showing the first eight; more decompositions exist.
