Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546236, here are decompositions:

5 + 31546231 = 31546236
19 + 31546217 = 31546236
37 + 31546199 = 31546236
83 + 31546153 = 31546236
107 + 31546129 = 31546236
167 + 31546069 = 31546236
173 + 31546063 = 31546236
223 + 31546013 = 31546236

Showing the first eight; more decompositions exist.
