Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015442, here are decompositions:

19 + 1015423 = 1015442
73 + 1015369 = 1015442
79 + 1015363 = 1015442
271 + 1015171 = 1015442
283 + 1015159 = 1015442
349 + 1015093 = 1015442
433 + 1015009 = 1015442
811 + 1014631 = 1015442

Showing the first eight; more decompositions exist.
