Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544104, here are decompositions:

5 + 31544099 = 31544104
47 + 31544057 = 31544104
71 + 31544033 = 31544104
83 + 31544021 = 31544104
107 + 31543997 = 31544104
113 + 31543991 = 31544104
191 + 31543913 = 31544104
197 + 31543907 = 31544104

Showing the first eight; more decompositions exist.
