Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152768, here are decompositions:

97 + 152671 = 152768
127 + 152641 = 152768
139 + 152629 = 152768
151 + 152617 = 152768
229 + 152539 = 152768
307 + 152461 = 152768
349 + 152419 = 152768
379 + 152389 = 152768

Showing the first eight; more decompositions exist.
