Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546842, here are decompositions:

11 + 31546831 = 31546842
29 + 31546813 = 31546842
43 + 31546799 = 31546842
53 + 31546789 = 31546842
83 + 31546759 = 31546842
101 + 31546741 = 31546842
179 + 31546663 = 31546842
181 + 31546661 = 31546842

Showing the first eight; more decompositions exist.
