Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43490, here are decompositions:

3 + 43487 = 43490
79 + 43411 = 43490
199 + 43291 = 43490
229 + 43261 = 43490
283 + 43207 = 43490
313 + 43177 = 43490
331 + 43159 = 43490
373 + 43117 = 43490

Showing the first eight; more decompositions exist.
