Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012442, here are decompositions:

3 + 1012439 = 1012442
19 + 1012423 = 1012442
31 + 1012411 = 1012442
43 + 1012399 = 1012442
73 + 1012369 = 1012442
163 + 1012279 = 1012442
181 + 1012261 = 1012442
229 + 1012213 = 1012442

Showing the first eight; more decompositions exist.
