Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051742, here are decompositions:

79 + 1051663 = 1051742
103 + 1051639 = 1051742
151 + 1051591 = 1051742
193 + 1051549 = 1051742
199 + 1051543 = 1051742
271 + 1051471 = 1051742
283 + 1051459 = 1051742
409 + 1051333 = 1051742

Showing the first eight; more decompositions exist.
