Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017842, here are decompositions:

43 + 1017799 = 1017842
61 + 1017781 = 1017842
139 + 1017703 = 1017842
193 + 1017649 = 1017842
229 + 1017613 = 1017842
283 + 1017559 = 1017842
523 + 1017319 = 1017842
541 + 1017301 = 1017842

Showing the first eight; more decompositions exist.
