Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152800, here are decompositions:

17 + 152783 = 152800
23 + 152777 = 152800
47 + 152753 = 152800
71 + 152729 = 152800
83 + 152717 = 152800
233 + 152567 = 152800
269 + 152531 = 152800
281 + 152519 = 152800

Showing the first eight; more decompositions exist.
