Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546860, here are decompositions:

13 + 31546847 = 31546860
17 + 31546843 = 31546860
29 + 31546831 = 31546860
43 + 31546817 = 31546860
47 + 31546813 = 31546860
53 + 31546807 = 31546860
61 + 31546799 = 31546860
71 + 31546789 = 31546860

Showing the first eight; more decompositions exist.
