Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61428, here are decompositions:

11 + 61417 = 61428
19 + 61409 = 61428
47 + 61381 = 61428
71 + 61357 = 61428
89 + 61339 = 61428
97 + 61331 = 61428
131 + 61297 = 61428
137 + 61291 = 61428

Showing the first eight; more decompositions exist.
