Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136420, here are decompositions:

3 + 136417 = 136420
17 + 136403 = 136420
23 + 136397 = 136420
41 + 136379 = 136420
47 + 136373 = 136420
59 + 136361 = 136420
83 + 136337 = 136420
101 + 136319 = 136420

Showing the first eight; more decompositions exist.
