Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61420, here are decompositions:

3 + 61417 = 61420
11 + 61409 = 61420
17 + 61403 = 61420
41 + 61379 = 61420
89 + 61331 = 61420
137 + 61283 = 61420
167 + 61253 = 61420
197 + 61223 = 61420

Showing the first eight; more decompositions exist.
