Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151338, here are decompositions:

59 + 151279 = 151338
97 + 151241 = 151338
101 + 151237 = 151338
137 + 151201 = 151338
149 + 151189 = 151338
167 + 151171 = 151338
181 + 151157 = 151338
197 + 151141 = 151338

Showing the first eight; more decompositions exist.
