Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989146, here are decompositions:

23 + 989123 = 989146
47 + 989099 = 989146
167 + 988979 = 989146
269 + 988877 = 989146
317 + 988829 = 989146
383 + 988763 = 989146
419 + 988727 = 989146
503 + 988643 = 989146

Showing the first eight; more decompositions exist.
