Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535254, here are decompositions:

41 + 31535213 = 31535254
71 + 31535183 = 31535254
83 + 31535171 = 31535254
131 + 31535123 = 31535254
173 + 31535081 = 31535254
197 + 31535057 = 31535254
293 + 31534961 = 31535254
383 + 31534871 = 31535254

Showing the first eight; more decompositions exist.
