Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989372, here are decompositions:

19 + 989353 = 989372
31 + 989341 = 989372
79 + 989293 = 989372
199 + 989173 = 989372
313 + 989059 = 989372
409 + 988963 = 989372
421 + 988951 = 989372
463 + 988909 = 989372

Showing the first eight; more decompositions exist.
