Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64144, here are decompositions:

53 + 64091 = 64144
107 + 64037 = 64144
131 + 64013 = 64144
137 + 64007 = 64144
167 + 63977 = 64144
281 + 63863 = 64144
383 + 63761 = 64144
401 + 63743 = 64144

Showing the first eight; more decompositions exist.
