Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535344, here are decompositions:

3 + 31535341 = 31535344
17 + 31535327 = 31535344
23 + 31535321 = 31535344
131 + 31535213 = 31535344
173 + 31535171 = 31535344
263 + 31535081 = 31535344
311 + 31535033 = 31535344
383 + 31534961 = 31535344

Showing the first eight; more decompositions exist.
