Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985430, here are decompositions:

13 + 985417 = 985430
31 + 985399 = 985430
79 + 985351 = 985430
139 + 985291 = 985430
151 + 985279 = 985430
211 + 985219 = 985430
367 + 985063 = 985430
373 + 985057 = 985430

Showing the first eight; more decompositions exist.
