Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103580, here are decompositions:

3 + 103577 = 103580
7 + 103573 = 103580
13 + 103567 = 103580
19 + 103561 = 103580
31 + 103549 = 103580
97 + 103483 = 103580
109 + 103471 = 103580
157 + 103423 = 103580

Showing the first eight; more decompositions exist.
