Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64428, here are decompositions:

29 + 64399 = 64428
47 + 64381 = 64428
101 + 64327 = 64428
109 + 64319 = 64428
127 + 64301 = 64428
149 + 64279 = 64428
157 + 64271 = 64428
191 + 64237 = 64428

Showing the first eight; more decompositions exist.
