Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544086, here are decompositions:

29 + 31544057 = 31544086
47 + 31544039 = 31544086
53 + 31544033 = 31544086
89 + 31543997 = 31544086
107 + 31543979 = 31544086
173 + 31543913 = 31544086
179 + 31543907 = 31544086
227 + 31543859 = 31544086

Showing the first eight; more decompositions exist.
