Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000442, here are decompositions:

13 + 1000429 = 1000442
19 + 1000423 = 1000442
61 + 1000381 = 1000442
109 + 1000333 = 1000442
139 + 1000303 = 1000442
151 + 1000291 = 1000442
193 + 1000249 = 1000442
211 + 1000231 = 1000442

Showing the first eight; more decompositions exist.
