Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121370, here are decompositions:

3 + 121367 = 121370
13 + 121357 = 121370
19 + 121351 = 121370
37 + 121333 = 121370
43 + 121327 = 121370
61 + 121309 = 121370
79 + 121291 = 121370
103 + 121267 = 121370

Showing the first eight; more decompositions exist.
