Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153018, here are decompositions:

17 + 153001 = 153018
29 + 152989 = 153018
37 + 152981 = 153018
59 + 152959 = 153018
71 + 152947 = 153018
79 + 152939 = 153018
109 + 152909 = 153018
139 + 152879 = 153018

Showing the first eight; more decompositions exist.
