Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64442, here are decompositions:

3 + 64439 = 64442
43 + 64399 = 64442
61 + 64381 = 64442
109 + 64333 = 64442
139 + 64303 = 64442
163 + 64279 = 64442
211 + 64231 = 64442
271 + 64171 = 64442

Showing the first eight; more decompositions exist.
