Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544116, here are decompositions:

17 + 31544099 = 31544116
59 + 31544057 = 31544116
83 + 31544033 = 31544116
137 + 31543979 = 31544116
239 + 31543877 = 31544116
257 + 31543859 = 31544116
269 + 31543847 = 31544116
347 + 31543769 = 31544116

Showing the first eight; more decompositions exist.
