Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543860, here are decompositions:

13 + 31543847 = 31543860
17 + 31543843 = 31543860
31 + 31543829 = 31543860
43 + 31543817 = 31543860
83 + 31543777 = 31543860
97 + 31543763 = 31543860
109 + 31543751 = 31543860
137 + 31543723 = 31543860

Showing the first eight; more decompositions exist.
