Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103644, here are decompositions:

31 + 103613 = 103644
53 + 103591 = 103644
61 + 103583 = 103644
67 + 103577 = 103644
71 + 103573 = 103644
83 + 103561 = 103644
173 + 103471 = 103644
193 + 103451 = 103644

Showing the first eight; more decompositions exist.
