Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37644, here are decompositions:

11 + 37633 = 37644
37 + 37607 = 37644
53 + 37591 = 37644
71 + 37573 = 37644
73 + 37571 = 37644
83 + 37561 = 37644
97 + 37547 = 37644
107 + 37537 = 37644

Showing the first eight; more decompositions exist.
