Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121608, here are decompositions:

17 + 121591 = 121608
29 + 121579 = 121608
31 + 121577 = 121608
37 + 121571 = 121608
61 + 121547 = 121608
101 + 121507 = 121608
107 + 121501 = 121608
139 + 121469 = 121608

Showing the first eight; more decompositions exist.
