Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152100, here are decompositions:

7 + 152093 = 152100
17 + 152083 = 152100
19 + 152081 = 152100
23 + 152077 = 152100
37 + 152063 = 152100
59 + 152041 = 152100
61 + 152039 = 152100
71 + 152029 = 152100

Showing the first eight; more decompositions exist.
