Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43290, here are decompositions:

7 + 43283 = 43290
19 + 43271 = 43290
29 + 43261 = 43290
53 + 43237 = 43290
67 + 43223 = 43290
83 + 43207 = 43290
89 + 43201 = 43290
101 + 43189 = 43290

Showing the first eight; more decompositions exist.
