Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985380, here are decompositions:

29 + 985351 = 985380
41 + 985339 = 985380
73 + 985307 = 985380
79 + 985301 = 985380
89 + 985291 = 985380
101 + 985279 = 985380
103 + 985277 = 985380
127 + 985253 = 985380

Showing the first eight; more decompositions exist.
