Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3578, here are decompositions:

7 + 3571 = 3578
19 + 3559 = 3578
31 + 3547 = 3578
37 + 3541 = 3578
61 + 3517 = 3578
67 + 3511 = 3578
79 + 3499 = 3578
109 + 3469 = 3578

Showing the first eight; more decompositions exist.
