Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61644, here are decompositions:

7 + 61637 = 61644
13 + 61631 = 61644
17 + 61627 = 61644
31 + 61613 = 61644
41 + 61603 = 61644
61 + 61583 = 61644
83 + 61561 = 61644
97 + 61547 = 61644

Showing the first eight; more decompositions exist.
