Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43578, here are decompositions:

5 + 43573 = 43578
37 + 43541 = 43578
61 + 43517 = 43578
79 + 43499 = 43578
97 + 43481 = 43578
127 + 43451 = 43578
137 + 43441 = 43578
151 + 43427 = 43578

Showing the first eight; more decompositions exist.
