Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121922, here are decompositions:

13 + 121909 = 121922
79 + 121843 = 121922
211 + 121711 = 121922
313 + 121609 = 121922
331 + 121591 = 121922
421 + 121501 = 121922
571 + 121351 = 121922
601 + 121321 = 121922

Showing the first eight; more decompositions exist.
