Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43580, here are decompositions:

3 + 43577 = 43580
7 + 43573 = 43580
37 + 43543 = 43580
139 + 43441 = 43580
181 + 43399 = 43580
373 + 43207 = 43580
379 + 43201 = 43580
421 + 43159 = 43580

Showing the first eight; more decompositions exist.
