Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103578, here are decompositions:

5 + 103573 = 103578
11 + 103567 = 103578
17 + 103561 = 103578
29 + 103549 = 103578
67 + 103511 = 103578
107 + 103471 = 103578
127 + 103451 = 103578
157 + 103421 = 103578

Showing the first eight; more decompositions exist.
