Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151506, here are decompositions:

7 + 151499 = 151506
23 + 151483 = 151506
29 + 151477 = 151506
73 + 151433 = 151506
83 + 151423 = 151506
109 + 151397 = 151506
127 + 151379 = 151506
149 + 151357 = 151506

Showing the first eight; more decompositions exist.
