Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153850, here are decompositions:

101 + 153749 = 153850
107 + 153743 = 153850
131 + 153719 = 153850
149 + 153701 = 153850
227 + 153623 = 153850
239 + 153611 = 153850
293 + 153557 = 153850
317 + 153533 = 153850

Showing the first eight; more decompositions exist.
