Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151700, here are decompositions:

7 + 151693 = 151700
13 + 151687 = 151700
19 + 151681 = 151700
97 + 151603 = 151700
103 + 151597 = 151700
127 + 151573 = 151700
139 + 151561 = 151700
151 + 151549 = 151700

Showing the first eight; more decompositions exist.
