Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151454, here are decompositions:

3 + 151451 = 151454
31 + 151423 = 151454
73 + 151381 = 151454
97 + 151357 = 151454
151 + 151303 = 151454
181 + 151273 = 151454
211 + 151243 = 151454
241 + 151213 = 151454

Showing the first eight; more decompositions exist.
