Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153420, here are decompositions:

11 + 153409 = 153420
13 + 153407 = 153420
41 + 153379 = 153420
61 + 153359 = 153420
67 + 153353 = 153420
83 + 153337 = 153420
101 + 153319 = 153420
107 + 153313 = 153420

Showing the first eight; more decompositions exist.
