Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558104, here are decompositions:

23 + 31558081 = 31558104
31 + 31558073 = 31558104
41 + 31558063 = 31558104
47 + 31558057 = 31558104
107 + 31557997 = 31558104
167 + 31557937 = 31558104
173 + 31557931 = 31558104
223 + 31557881 = 31558104

Showing the first eight; more decompositions exist.
