Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31578114, here are decompositions:

5 + 31578109 = 31578114
13 + 31578101 = 31578114
23 + 31578091 = 31578114
47 + 31578067 = 31578114
137 + 31577977 = 31578114
163 + 31577951 = 31578114
173 + 31577941 = 31578114
317 + 31577797 = 31578114

Showing the first eight; more decompositions exist.
