Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611300, here are decompositions:

29 + 31611271 = 31611300
113 + 31611187 = 31611300
137 + 31611163 = 31611300
163 + 31611137 = 31611300
173 + 31611127 = 31611300
199 + 31611101 = 31611300
211 + 31611089 = 31611300
233 + 31611067 = 31611300

Showing the first eight; more decompositions exist.
