Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43538, here are decompositions:

97 + 43441 = 43538
127 + 43411 = 43538
139 + 43399 = 43538
277 + 43261 = 43538
331 + 43207 = 43538
337 + 43201 = 43538
349 + 43189 = 43538
379 + 43159 = 43538

Showing the first eight; more decompositions exist.
