Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987434, here are decompositions:

43 + 987391 = 987434
73 + 987361 = 987434
223 + 987211 = 987434
241 + 987193 = 987434
307 + 987127 = 987434
337 + 987097 = 987434
367 + 987067 = 987434
373 + 987061 = 987434

Showing the first eight; more decompositions exist.
