Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042538, here are decompositions:

19 + 1042519 = 1042538
139 + 1042399 = 1042538
157 + 1042381 = 1042538
181 + 1042357 = 1042538
229 + 1042309 = 1042538
271 + 1042267 = 1042538
397 + 1042141 = 1042538
439 + 1042099 = 1042538

Showing the first eight; more decompositions exist.
