Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123850, here are decompositions:

17 + 123833 = 123850
29 + 123821 = 123850
47 + 123803 = 123850
59 + 123791 = 123850
113 + 123737 = 123850
131 + 123719 = 123850
149 + 123701 = 123850
173 + 123677 = 123850

Showing the first eight; more decompositions exist.
