Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543836, here are decompositions:

7 + 31543829 = 31543836
19 + 31543817 = 31543836
53 + 31543783 = 31543836
59 + 31543777 = 31543836
67 + 31543769 = 31543836
73 + 31543763 = 31543836
113 + 31543723 = 31543836
139 + 31543697 = 31543836

Showing the first eight; more decompositions exist.
