Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544308, here are decompositions:

11 + 31544297 = 31544308
101 + 31544207 = 31544308
137 + 31544171 = 31544308
251 + 31544057 = 31544308
269 + 31544039 = 31544308
311 + 31543997 = 31544308
317 + 31543991 = 31544308
347 + 31543961 = 31544308

Showing the first eight; more decompositions exist.
