Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009442, here are decompositions:

3 + 1009439 = 1009442
43 + 1009399 = 1009442
73 + 1009369 = 1009442
139 + 1009303 = 1009442
151 + 1009291 = 1009442
199 + 1009243 = 1009442
241 + 1009201 = 1009442
283 + 1009159 = 1009442

Showing the first eight; more decompositions exist.
