Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544236, here are decompositions:

23 + 31544213 = 31544236
29 + 31544207 = 31544236
47 + 31544189 = 31544236
83 + 31544153 = 31544236
137 + 31544099 = 31544236
179 + 31544057 = 31544236
197 + 31544039 = 31544236
239 + 31543997 = 31544236

Showing the first eight; more decompositions exist.
