Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526842, here are decompositions:

5 + 526837 = 526842
11 + 526831 = 526842
13 + 526829 = 526842
61 + 526781 = 526842
79 + 526763 = 526842
83 + 526759 = 526842
101 + 526741 = 526842
103 + 526739 = 526842

Showing the first eight; more decompositions exist.
